What is AISI 4140 Steel? AISI 4140 alloy steel round bar sheet plate belongs to medium hardenability steel.AISI 4140 steel has high fatigue strength and low notch sensitivity. Low- temperature impact toughness is also very high, no obvious temper brittleness. AISI 4140 steel round bar is mainly used after quenching and tempering state. it is used to manufacture high-strength parts under impact loads and the fittings with large cross-sections and other stressed members. Such as the horizontal eccentric shaft of the horizontal forging machine, the crankshaft of the forging press, and etc. Its equivalent grade is JIS SCM440 and DIN 1.7225. The properties and composition of 4140 steel round bar sheet plate as below. AVAILABLE SIZE: Round bar: Diameter(mm) Max 800mm; Length(mm) Max 12000mm. Plate: Thickness(mm) Max 800mm; Width(mm) Max 2300mm; Length(mm) Max 12000mm. Condition: Cold rolled(drawn)≤50mm, Hot rolled≤12-250mm, Hot forged≥50mm. AISI 4140/DIN 1.7225 Introduction: AISI 4140 alloy steel is chromium, molybdenum, manganese containing low alloy steel. It has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength. Fabrication and Heat Treatment: 1. Forging Preheat the steel carefully, then raise the temperature to 1150-1200°C for forging. Do not forge below 850°C. 2. Annealing Heat the AISI 4140 slowly to 800-850°C and allow enough time for the steel to be thoroughly heated. Cool slowly in the furnace to 480°C followed by air cooling. 3. Stress Relieving When parts are heavily machined, ground or otherwise subject to cold work, stress relieving will be beneficial prior to hardening. 4. Hardening AISI 4140 steel is usually supplied ready heat treated to 18-22HRC. If further heat treatment is required annealed AISI 4140 should be heated slowly to 840- 875°C and after adequate soaking at this temperature quench in oil. Temper as soon as the tools reach room temperature. 5. Tempering Heat the AISI 4140 carefully to a suitable temperature selected by reference to a tempering chart or table (usually between 550-700°C, soak at the temperature for 2 hours per 25mm of ruling section, then allow to cool in air. Tempering between 250-375°C is not advised as tempering within this range will seriously reduce the impact value. 6. Surface Treatment Plate: Origin Black, Orign cold rolled bright, Machined, Grinded Bar: Origin Black, Orign cold rolled(drawn) bright, Turned, Peeled, Grinded Songshun specialized in Special Steel for almost 20 years.

Some silver will be added during the processing of lead-free silver-containing tin wire. The main function of silver is to enhance conductivity. The role of silver is to enhance its electrical conductivity. Although the main component of lead-free tin wire is tin, there are also other components of metal. Tin wire is mainly divided into lead tin wire and lead-free tin wire. With the development of social economy, more and more electronic processing factories choose lead-free tin wire. Lead-free tin wire meets the ROHS standard proposed by the European Union's environmental protection requirements. Solder is made of tin-copper, tin-silver-copper and other alloys. There is also lead-free tin wire with silver added in order to increase the gloss, the brightness is better, it has good wettability, electrical conductivity, thermal conductivity, and it is easy to tin. All environmentally friendly products in our factory have ROHS certificates, and environmental testing reports and factory reports can be attached to the factory to ensure product quality.We can provide customized products in different purities and sizes to meet different needs. https://www.star-sn.com/product/china_ti , n_wire

Floating extruded fish feed has the advantages of convenient management, high nutritional value, good stability, and less water pollution. If you want to produce high-quality extruded feed, you need not only a high-quality fish pellet machine but also advanced floating fish feed processing technology for support. At present, the more advanced puffing process is attributed to high temperature, high pressure, high humidity, and short-time puffing, which is especially suitable for processing vegetable protein and starch raw materials for animal feed. The fish food pellets produced by our fish food pellet extruder have been fully cooked and sterilized, so the fish is not easy to get sick after eating, and will not have any side effects. And according to customer needs, our fish food pellet machine can produce fish food pellets of different sizes by changing the mold to adapt to different sizes of fry. Fish food pellets are generally divided into 1-6mm, which can meet the size requirements of most fish fries. https://www.limafeedpelletizer.com/float , ing-fish-feed-pelleting-machine/
