What is the s355j2 pipe equivalent grades

BBN steel company was founded in 2000, starting the international business in 2010 and successfully being approved and certified by ISO9001:2008. After ten years development, BBN steel has become the large-scale comprehensive enterprise group, combining steel trading, s355j2 pipe plate processing, and steel distribution, also have large warehouse and processional representatives both inTianJin, Zhengzhou and Beijing city.

Q690D steel belongs to high-strength welded structural steel. Among them, Q represents the yield strength, 690 represents the yield strength value, and D represents the grade of the steel plate. The quality grades of common Q690 series steel are A, B, C, D, E. The impact of grade D steel plate is -20°C. Q690D steel can be called a low temperature resistant high strength steel with a yield strength of 690Mpa.

Special boiler steel is derived from carbon structural steel. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same level, but the s355j2 pipe steel mechanical property requirements are more strict, especially for impact toughness. And the aging sensitivity is required to be small. The boiler steel should be deoxidized and the non-metallic inclusions should be removed during smelting. The structure should be uniform. The grain size should be controlled in 3-7 grades. The defects such as interlayer, shrinkage, porosity and porosity should be minimized.

Alloying agents like carbon and manganese along with steel lends a malleable nature to A572 structural high tensile steel plates, s355j2 pipe, letting them be formed into various structurals that adapt quickly to constantly evolving needs of an edifice, thereby being flexible to changes. High tensile steel plates facilitate an increased load bearing capacity; their lighter bodies handle the extra weight without giving in to pressures. Heavy lifting and moving vehicles built from them increase weight bearing capacity, reduce time and labour cost to increase profits.

s355j2 pipe, 13CrMo44 steel plate is a kind of steel which with Cr, Mo,Cr-Mo and mainly used for pressure vessels. The steel grade 13CrMo44 is according to DIN 17155 standard which with the yield strength of 242MPa. The DIN 17155 13CrMo44 steel plate chemical composition is the content of C is 0.15, Mn is 2.00, S is 0.03, Cu is 0.30, Si is 1.00, P is 0.045, Cr is 17 or 19 and the Ni is 8 or 10.

Over the years, the company has maintained long-term stable business relationships with major domestic steel mills and foreign steel companies. The company's main boiler and pressure vessel steel plates, low alloy high-strength steel plates, wear-resistant steel plates, corrosion-resistant steel plates, s355j2 pipe bridge steel plates , strucural teel plates, steel plates for alloy structures, mold steel plates, steel plates for shipbuilding and production platforms, composite steel plates, steel plates for oil and gas pipelines.
