420 stainless steel arc spraying wire is a high-cost-performance alloy spraying material provided by a professional alloy trading company, tailored to core industrial needs. Made from 420 martensitic stainless steel raw materials with a purity of over 99.9%, the wire undergoes precision wire drawing, vacuum annealing, and precision straightening processes to ensure inherent performance stability. During arc spraying, it forms a coating with a density of ≥95% and a coating-substrate bonding strength of ≥35MPa, effectively resolving industry pain points such as paper roll wear and metal substrate corrosion in harsh environments. Leveraging our direct procurement supply chain, we offer factory- direct pricing, and also support bulk customization and small-batch trial orders to meet the diverse procurement and application demands of different customers. Product Features Superior corrosion resistance: 13-14% chromium content forms a protective passivation film, extending the substrate’s anti-corrosion cycle by 3-5 times. High wear resistance & restoration capability: Coating microhardness reaches HV550-700, enabling 0.1-5mm precise thickness restoration for damaged paper rolls. Excellent process compatibility: ±0.02mm diameter tolerance, stable melting and arc combustion, ≤3% splash rate, and compatibility with mainstream spraying equipment. Outstanding cost-effectiveness: Factory-direct pricing, ≤2% loss rate, 1.2-1.5 ㎡ coverage per kg, and 15-20% lower comprehensive cost than similar products. Environmental compliance: Complies with ISO 9001 and RoHS standards, free of harmful impurities and toxic emissions after spraying. Stable batch consistency: Three full inspections per batch ensure uniform diameter, hardness, and composition of products. Product Applications Paper roll restoration & strengthening: Repairs and reinforces papermaking machine rolls (press, guide, coating rolls), restoring roundness error to ≤0.02mm and extending service life by over 3 times. General metal substrate corrosion protection: Protects carbon steel, cast iron and other substrates in machinery, chemical, marine, and bridge fields from oxidation and chemical erosion. Wear-resistant component strengthening: Increases the surface hardness of mining, agricultural, and printing equipment parts by 2-3 times, reducing wear and replacement costs. Special industry applications: Applicable to automotive chassis repair, medical device protection, electronic shell corrosion prevention, and food machinery surface strengthening.

https://www.yyvalveball.com/productstags/carbi , de-valve-ball.html Introduction High-precision tungsten-cobalt cemented carbide balls are widely used in oil drilling and deep-sea drilling oil pump valve balls and ball seats, which are also one of the most critical components in oil pumps. Due to the harsh working environment and conditions in the oil drilling industry, sand-containing wells, heavy oil wells, and high-pressure anti-oil wells usually contain water, various gases, wax, sand and other highly corrosive substances. The oil pump needs to extract oil from hundreds or even thousands of meters of formations, which requires its valve ball and valve seat to have good sealing, wear resistance and corrosion resistance (the valve ball and valve seat are vacuumed to an absolute pressure of less than 0.36kgN/cm after matching, and the absolute pressure value does not change within 10s). Advantages 1. It has the lowest theoretical flow resistance (flow resistance refers to the ratio of the pressure difference on both sides of the sound-absorbing material sample to the linear velocity of the airflow passing through the sample under stable airflow conditions.); 2. Excellent chemical stability and wear and corrosion resistance, can be in contact with most liquids and some corrosive media; 3. Under high temperature and high pressure environment, it can still achieve complete sealing (nominal pressure from vacuum to 42MPa); 4. Since the carbide ball valve uses the ball as the opening and closing part, it is less affected by friction and can achieve fast opening and closing (can be controlled within 0.05-0.1s), and the operation has less impact. In addition, the spherical closing part can withstand a higher pressure difference when closing, and can also achieve automatic positioning; 5. It has bidirectional sealing, making the work more stable and reliable. Applicable 1. Carbide ball valves are suitable for use in two-position adjustment, pipeline systems with high requirements for sealing performance, rapid opening and closing (1/4 turn opening and closing), large pressure difference, small operating torque, small flow resistance, and cavitation or vaporization phenomena; 2. Pipes with certain corrosive media; 3. In low-temperature deep-freezing devices or high-temperature and high- pressure pipeline systems; 4. Full-bore welded carbide ball valves can be used in oil pipelines and gas pipelines that need to be buried underground; 5.Specially designed V-shaped opening structure carbide ball valves can also have certain adjustment functions.
