comparison of S355K2 steel and A573 Grade 70 steel material spec

In terms of service, our service is a "one-stop" way of working. We have our own comparison of S355K2 steel and A573 Grade 70 steel processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as comparison of S355K2 steel and A573 Grade 70 steel cutting, welding, drilling, galvanizing, etc., at the lowest cost.

42CrMo4 material is an alloy structural steel with high strength, high hardenability, good toughness, small deformation during quenching, and high creep strength and endurance strength at high temperatures. 42CrMo4 steel is a modified AISI 4140 steel. The comparison of S355K2 steel and A573 Grade 70 steel product is mainly used in the manufacturing of seamless hydraulic cylinder or gas cylinder, heavy machinery, cranes, excavators and forklifts, etc.

The cold working performance of comparison of S355K2 steel and A573 Grade 70 steel and so on steel structure engineering steel is good, which can ensure that the steel will not crack or brittle fracture during high-temperature processing, and will not have a great impact on strength, plasticity and toughness due to processing. The durability of comparison of S355K2 steel and A573 Grade 70 steel and so on steel structure engineering steel is good. Durability refers to the service life of steel structure. The main factor affecting the service life of steel is the poor corrosion resistance of steel, followed by the deterioration of mechanical properties of steel under long-term load, repeated load and dynamic load.

The primary purpose of adding alloy elements into steel is to improve the hardenability of steel and to ensure that martensite can be easily obtained during quenching. The second is to improve the tempering stability of the steel, to keep the martensite at a higher temperature, so that the carbide precipitated in the tempered steel is finer, uniform and stable. In this way, under the same conditions, comparison of S355K2 steel and A573 Grade 70 steel, alloy steel has higher strength than carbon steel. One of the main purposes of adding alloy elements is to improve the strength of steel.

BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the comparison of S355K2 steel and A573 Grade 70 steel hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.
