Big mill hot rolled 09CuPCrNi-A equivalent grades

Characteristics of 50CrMo4 steel: 50CrMo4 steel has high strength and toughness, good hardenability and no obvious tempering brittleness. 50CrMo4 steel is suitable for manufacturing large and medium-sized plastic mould with certain strength and toughness. 50CrMo4 steel can be used to manufacture the big gear for locomotive traction, booster drive gear, 09CuPCrNi-A equivalent grades pressure vessel gear, rear axle, connecting rod and spring clamp with great load, as well as the drill pipe joint and fishing tool for oil deep well below 2000m, and 50CrMo4 steel can also be used for the die of bending machine, etc.

09CuPCrNi-A equivalent grades, Q345D seamless pipe is low-alloy high-strength structural steel. It is named as low-alloy because of a small amount of alloy elements in the steel. Q345D seamless pipe is mainly used for construction and engineering structures. The carbon content of Q345D seamless pipe is ≤ 0.18%. Due to the effect of alloy elements, the yield strength of Q345D seamless pipe is 25% - 150% higher than that of carbon structural steel pipe with the same carbon content. Q345D seamless pipe can reduce the weight of steel structure, save steel products and effectively extend the service life of steel structure.

The preparation of 09CuPCrNi-A equivalent grades galvanized steel before welding is the same as that of ordinary low-carbon steel. It is necessary to carefully handle the groove size and nearby galvanized layer. In order to achieve penetration, the groove size shall be appropriate, generally 60 ~ 65 °, with a certain gap, generally 1.5 ~ 2.5mm; in order to reduce the penetration of zinc into the weld, the galvanized layer in the groove can be removed before welding. In the practical work, the centralized beveling, no blunt edge technology for 09CuPCrNi-A equivalent grades centralized control, two-layer welding process, reducing the possibility of incomplete penetration.

The high strength 09CuPCrNi-A equivalent grades 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 09CuPCrNi-A equivalent grades ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
