20# steel is carbon steel with carbon content of about 0.20%. It belongs to low carbon steel with high quality. The equivalent material of 20# steel is S20C. 20# steel has low strength and hardness, good plasticity and toughness, good carburizing effect and good weldability. 20# steel is often used to make pressure parts (such as gasket, chain piece), carburizing parts (gear, CAM), welding parts, plastic mold, etc.
The results of adopting two-level mild steel plate ASTM A36 ST37 ST52 service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and mild steel plate ASTM A36 ST37 ST52 after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.
Compared with 45 steel, the annealed hardness of 40Cr is about 10hbw higher; The normalized state is about 24 HBW higher than the normalized state; After quenching and tempering at 600℃, the hardness is about 70hbw higher than that of the steel. Therefore, in stainless steel engineering, most mild steel plate ASTM A36 ST37 ST52 alloy steels are generally used after quenching and tempering.
Based on the principle of quality and respect for customers, BBNsteel maintains good cooperative relations with customers in home and abroad. With modern management, high-quality products, reasonable prices and comprehensive after-sales service, we provide our customers with high quality and low price mild steel plate ASTM A36 ST37 ST52 products.
