ASTM A240 / ASME SA240 Type 321 Stainless Steel Plate (UNS S32100) - China Mill-Direct Supply 1. Product Introduction SHH STEEL (Shanghai Shenghonghe Import & Export Co., Ltd.) supplies ASTM A240 / ASME SA240 Type 321 Stainless Steel Plate. ASTM A240 Type 321 is a titanium-stabilized austenitic chromium-nickel stainless steel offering excellent intergranular corrosion resistance and good high-temperature performance. Titanium combines preferentially with carbon to form stable titanium carbides, preventing chromium carbide precipitation at grain boundaries when the steel is exposed to the sensitisation range (roughly 425-815 C) during welding or in service. This makes 321 well suited to equipment operating intermittently or continuously at elevated temperatures, where it also provides good oxidation resistance and creep strength. It has good formability and weldability, is non-magnetic in the annealed condition, and is delivered solution annealed. Typical applications include aerospace and automotive (including exhaust systems), chemical and petrochemical plants, power generation, heat treatment equipment, pressure vessels, refineries and general fabrication. Available surface finishes include No.1, 2B, 2D, BA, No.4, HL (Hairline) and 8K Mirror; protective PVC film can be applied on one or both sides for architectural or specific functional requirements. Product forms available include plate, sheet, coil, strip, foil, shim, circle and ring. 2. Standards We Can Supply ASTM A240 / ASME SA-240 (full compliance).

ASTM A240 / ASME SA240 Type 316 Stainless Steel Plate and Sheet (UNS S31600) 1. Product Introduction SHH STEEL (Shanghai Shenghonghe Import & Export Co., Ltd.) supplies ASTM A240 / ASME SA240 Type 316 Stainless Steel Plate and Sheet. ASTM A240 Type 316, also known as SS316 or UNS S31600, is a molybdenum- bearing austenitic stainless steel and one of the most widely used stainless steels in corrosive environments. Its 2-3% molybdenum addition gives enhanced pitting and crevice corrosion resistance in chloride-containing media such as seawater, de-icing salts and many process chemicals, outperforming 304-series grades. Type 316 also offers good strength at elevated temperatures, excellent formability and good weldability by common fusion welding processes. It is non- magnetic in the annealed condition and retains good toughness at low temperatures, making it a versatile choice for demanding process and marine duty. Typical applications include chemical processing, marine and coastal environments, the food and beverage industry, pharmaceutical and biotech, pulp and paper, architecture and construction, and general industrial equipment. Available surface finishes include No.1, 2B, 2D, BA, No.4, HL (Hairline) and 8K Mirror; protective PVC film can be applied on one or both sides for architectural or specific functional requirements. Product forms available include plate, sheet, coil, strip, foil, shim, circle and ring. 2. Standards We Can Supply ASTM A240 / ASME SA-240 (full compliance).

ASTM A240 / ASME SA240 Type 304L Stainless Steel Plate and Sheet (UNS S30403) 1. Product Introduction SHH STEEL (Shanghai Shenghonghe Import & Export Co., Ltd.) supplies ASTM A240 / ASME SA240 Type 304L Stainless Steel Plate and Sheet. ASTM A240 Type 304L, also known as SS304L, UNS S30403 or SUS304L, is the low-carbon version of Type 304, designed under the ASTM A240 / ASME SA240 specification to provide superior resistance to intergranular corrosion after welding. The maximum carbon content of 0.03% significantly reduces the risk of carbide precipitation during welding, making 304L the preferred choice for welded pressure vessels, tanks and process equipment in corrosive environments. Like 304, it is an 18% chromium / 8% nickel class austenitic stainless steel with excellent formability, good toughness at low temperatures and a non-magnetic structure in the annealed condition. Heavy sections can usually be welded without post-weld annealing, which saves fabrication time and cost. Typical applications include welded pressure vessels, storage tanks, process equipment, chemical and food processing plants, piping fabrication and general welded structures. Available surface finishes include No.1, 2B, 2D, BA, No.4, HL (Hairline) and 8K Mirror; protective PVC film can be applied on one or both sides for architectural or specific functional requirements. Product forms available include plate, sheet, coil, strip, foil, shim, circle and ring. 2. Standards We Can Supply ASTM A240 / ASME SA-240 (full compliance). Dimensional tolerances and flatness follow ASTM A480; equivalent designations: UNS S30403 / EN 1.4306 / JIS SUS 304L / GB 022Cr19Ni10.

ASTM A240 / ASME SA240 Type 304 Stainless Steel Plate and Sheet (UNS S30400) 1. Product Introduction SHH STEEL (Shanghai Shenghonghe Import & Export Co., Ltd.) supplies ASTM A240 / ASME SA240 Type 304 Stainless Steel Plate and Sheet. ASTM A240 Type 304, also known as SS304, UNS S30400 or SUS304, is the most widely used austenitic stainless steel grade under the ASTM A240 / ASME SA240 specification. It offers an outstanding combination of corrosion resistance, formability, weldability and cost- effectiveness. Type 304 contains approximately 18% chromium and 8% nickel, providing excellent resistance to a wide range of atmospheric, chemical and food-processing environments. Its austenitic structure gives very good ductility and deep-drawing ability, it is non-magnetic in the annealed condition, and it retains good toughness at low temperatures. It is readily welded by common fusion welding methods and is suitable for both cold-formed sheet and hot-rolled plate applications, from thin decorative panels to heavy plate for tanks and pressure equipment. Typical applications include food and beverage equipment, chemical processing, architecture and construction, pressure vessels and tanks, and kitchen and sanitary equipment. Available surface finishes include No.1, 2B, 2D, BA, No.4, HL (Hairline) and 8K Mirror; protective PVC film can be applied on one or both sides for architectural or specific functional requirements.

ASTM A240 / ASME SA240 Type 316L Stainless Steel Plate and Sheet (UNS S31603) 1. Product Introduction SHH STEEL (Shanghai Shenghonghe Import & Export Co., Ltd.) supplies ASTM A240 / ASME SA240 Type 316L Stainless Steel Plate and Sheet. ASTM A240 Type 316L, also known as SS316L, UNS S31603 or SUS316L, is the low-carbon version of Type 316 and is specifically designed for welded constructions in corrosive environments. It is a molybdenum- bearing austenitic chromium-nickel stainless steel containing 2.00- 3.00% molybdenum, which greatly improves resistance to pitting and crevice corrosion in chloride-containing media compared with 304- series grades. The low carbon content (0.030% max) minimises carbide precipitation in the heat-affected zone, giving excellent resistance to intergranular corrosion after welding. 316L can be welded by all common fusion welding processes, including GTAW (TIG), GMAW (MIG), SMAW and plasma welding, without post-weld annealing in most cases; matching filler metals such as ER316L are recommended. In the solution-annealed condition it combines good strength with excellent ductility and toughness, with hardness of not more than 217 HB / 95 HRB and a density of 8.00 g/cm3. It is non-magnetic in the annealed condition and keeps good toughness down to cryogenic temperatures. Typical applications include chemical processing, marine and coastal environments, the food and beverage industry, pharmaceutical and biotech equipment, pulp and paper, architecture and construction, and general industrial welded equipment such as tanks, pressure vessels and piping systems. Available surface finishes include No.1, 2B, 2D, BA, No.4, HL (Hairline) and 8K Mirror; protective PVC film can be applied on one or both sides for architectural or specific functional requirements.
