What is the s355j2 pipe steel measurement

Vigorously develop circular economy: the company adheres to the development path of circular economy, realizes the efficient utilization of energy and s355j2 pipe resources, implements "four closed circuits" for renewable gas, industrial water, solid waste and waste heat steam according to the reduction of resource consumption - reuse - recycling, vigorously promotes advanced technologies such as energy-saving new technologies, new processes, s355j2 pipe new materials, and promotes the competition of enterprises Struggle.

AISI4140 steel plate is used to make forgings that require higher strength and larger quenched and tempered section than 35CrMo steel, such as large gears for locomotive traction, turbocharger transmission gears, pressure vessel gears, rear axles, connecting rods with extremely high loads, and Spring clip. It can also be used for oil deep well drill pipe joints and fishing tools below 2000m, and can be used for molds of bending machines.

Weather-resistant steel plate refers to steel plate that is resistant to weathering and corrosion. s355j2 pipe, Weather-resistant steel plate can adapt well to the environment and is widely used in construction, bridges, roads and other fields with outstanding performance characteristics. One of the outstanding advantages of weather-resistant steel plate is its ability to adapt to a variety of different environments, whether it is in severe cold areas or tropical areas. The weather-resistant steel plate can better maintain its characteristics in various complex environment.

Low alloy high strength steel plate is made by adding a small amount of alloy elements on the basis of carbon structural steel (carbon content 0.16% ~ 0.2%). s355j2 pipe, Low alloy high strength steel plate has good welding performance, plasticity, toughness and processing technology, good corrosion resistance, high strength and low critical transition temperature of cold embrittlement.

According to GBT3077, 42CrMo steel chemical composition should be within the range (%): 42CrMo carbon content is 0.38-0.45 (C), Silicon content is 0.17-0.37 (Si), Manganese content is 0.50-0.80 (Mn), Chrome content is 0.90-1.20 (Cr), Molybdenum content is 0.15-0.25 (Mo). The high Cr content contrivutes to high strength of 42CrMo steel, with min. yield strength of 930 Mpa, and min. tensile strength of 1080 Mpa. The common heat treatment for s355j2 pipe, 42CrMo steel is quenching and tempering.
