Grade S355J2WP steel number machinability

Zhengzhou BBN steel company was established in 2000. After more than ten years of development, it has formed a professional operation pattern integrating R&D, production, sales and after-sales service. In recent years, S355J2WP steel number based on a high starting point and high technology, the company has vigorously developed various steel products S355J2WP steel number and deep-processed parts, steel structures, precision castings, seamless pipes.

EN10025-3 S460NL material is a hot rolled low carbon manganese steel. It has min. 460Mpa yield strength and low temperature impacting at -50℃ with minimum energy 27 J. S355J2WP steel number, S460NL also has good weldable property and possess good impact resistance (also in sub-zero temperatures). We supply S460NL steel plate for deep oceans, bulit the tanks or structural parts of nuclear submarine all over the world. Large stock of S460NL hot rolled plate available in India, Bangladesh, Malaysia, Nigeria, South Africa & UAE.

We are one of the largest weathering steel stock keepers in China and even in the world. For most specs weathering steel materials, we can arrange delivery within 5 days. Meanwhile, our weathering steel price is competitive. And for weathering steel coils, we do slit, S355J2WP steel number plate cut and so on further processing. We can meet different size and shape needs of customers.

The wear-resistant plate has the main advantages of high strength and hardness, good toughness, S355J2WP steel number high tensile strength, good material wear-resistance, long service life and low cost. In order to verify the wear-resistant life of the high wear-resistant composite steel plate applied in the field, the comparative industrial test of S355J2WP steel number wear-resistant with the ordinary carbon plate was carried out on the reclaimer of Jigang raw material plant, and the effect is good.

20Mn2 steel has medium strength, and the properties of 20Mn2 steel and 20Cr steel are similar. The impact toughness and weldability of 20Mn2 steel at low temperature are better than those of 20Cr steel. The plasticity and machinability of 20Mn2 steel are high during cold deformation. The hardenability of 20Mn2 steel is higher than that of corresponding carbon steel, S355J2WP steel number. Chemical composition of 20Mn2 steel: C: 0.17-0.24, Si: 0.17-0.37, Mn: 1.40-1.80. Mechanical properties of 20Mn2 steel: tensile strength ≥ 785 MPa, yield strength ≥ 590 MPa, elongation after fracture ≥ 10%, section expansion rate ≥ 40%, impact absorbed energy ≥ 47J.
