What is the difference between ASME SA514 steel material and A36 metals?

ASME SA514 steel material,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.

Grade AH32/AH36, Grade DH32/DH36 high-strength structural steel products for hulls have good comprehensive mechanical properties, welding performance, good processing performance. Grade AH32/AH36 hull strucural steel is suitable for manufacturing structural parts such as ship hull structures, docks, oil production platforms, marine transmission pipelines, coastal power plants, wharf facilities, etc. in ocean, coastal and inland navigation areas.

After quenching and tempering, 40Cr alloy steel plate and sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.

With the increase of carbon content in the steel material, the yield point and tensile strength increase, but the plasticity and impact decrease. When the carbon content is more than 0.23%, the welding performance of the steel material becomes worse. Therefore, the carbon content of low alloy structural steel used for welding is generally less than 0.20%. The high carbon content can also reduce the atmospheric corrosion resistance of steel material, and the high carbon steel in the open air is easy to rust; in addition, carbon can increase the cold brittleness and aging sensitivity of steel material.

Q345 and Q345B are steel numbers The differences are as follows:1 Q345 is general and does not indicate the quality level; Q345B is clear and the quality level is B2 Q345 does not require to inspect the impact performance; Q345B requires that the impact performance at room temperature is qualified (impact at 20 ℃)3 Q345 does not indicate carbon content of steel; Q345B carbon content is 020%Q345 refers to carbon structural steel with yield point (σ s) of 345MPa The following letters indicate the quality level, including A, B, C, D and E,ASME SA514 steel material.

ASME SA514 steel material,our company is a professional ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel exporter and a steel Stockist in china. We keep more than 1000 tons ASTM A573 Grade 70/A573 Gr.70 carbon manganese silicon steel plates steel in stock every month.

ASME SA514 steel material,Over the years, the company has strived for perfection, being well-received.
