SMA400AP steel coils equivalent BS grade

The company adheres to the service concept of "you give the order to me and I leave the satisfaction to you". Over the years, our steel products are supplied in time, with reliable quality and perfect and thoughtful after-sales service. Meanwhile, we have huge steel stocks all the year round. The company long-term pursues the principle of quality first, customer first, quality for survival, reputation for development, and perfect service to win the users.

SMA400AP steel coils,Shipbuilding steel plates or offshore platform plates are used to make hulls, offshore oil production drilling, platform pipe joints and other structural parts; Our ship steel plates are nine classification societies certified( American ABS, French BV, British LR, German GL, Norwegian DNV, Italian RINA, Japanese NK, Chinese CCS, South Korea KR ). These plates can be Z15 / Z25 / Z35. Our company stocks a large number of shipbuilding plates, offshore platform plate steel in stock.

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This 20Cr alloy steel still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.

SMA400AP steel coils,Quenching is a common heat treatment process. It is the metal heat treatment process in which the metal workpiece is heated to a proper temperature and kept for a period of time, then immersed in the quenching medium for rapid cooling. Quenching can improve the strength and hardness of steel in a large range, and adjust the coordination between strength and hardness, plasticity and toughness. Quenching is generally used as the final heat treatment.

The high strength low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
