34crmo4 alloy steel for quenching and tempering us equivalent grades
API2WGr60 material is a special material for pipeline steel. It is mainly used to transport large-diameter welded steel pipes such as oil and natural gas for hot-rolled coils or thick and wide plates. In addition to high compressive strength, it also requires high low temperature toughness and excellent welding performance. As a leading supplier of 34crmo4 alloy steel for quenching and tempering, API2WGr60 pipeline steel plate in China, our company supply API2WGr60 steel plate, API2WGr60 steel stock and API2WGr60 steel pipe with favourable price.
Weathering steel is characterized in that the alloy composition and weight percentage content. The chemical composition C≤0.12, Si: 0.25 ～ 0.75, Mn: 0.20 ～ 0.50, P: 0.07 ～ 0.15, S≤0.03, Cu: 0.25 ～ 0.55 , Cr: 0.30 ～ 1.25, Ni≤0.65, and the rest are Fe and trace impurities. Weathering steel sheet 34crmo4 alloy steel for quenching and tempering is mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time.
Quenching and tempering (QT) is a double heat treatment process of quenching and high temperature tempering. In general, medium carbon steel and medium 34crmo4 alloy steel for quenching and tempering carbon alloy steel often need quenching and tempering treatment. Quenching and tempering can make iron and steel parts obtain a good combination of strength and toughness, with high strength, excellent toughness, plasticity, cutting performance, etc. Some 34crmo4 alloy steel for quenching and tempering alloy steel or low alloy steel must be quenched and tempered to obtain good comprehensive properties. These steels can also be called quenched and tempered steels.
The high strength 34crmo4 alloy steel for quenching and tempering 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 34crmo4 alloy steel for quenching and tempering ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
Both parties shall confirm the 34crmo4 alloy steel for quenching and tempering material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the 34crmo4 alloy steel for quenching and tempering steel plant.
