Based on the advantages of heat treatment of P355GH steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel heat treatment of p355gh products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .

S235JR is a European standard non alloy structural steel, equivalent to the national standard Q235B, i.e. S235JR steel is carbon structural steel with low carbon content. S235JR steel is widely used in welding, bolt connection and riveting structures. S235JR steel is mainly used in railway, bridge, all kinds of construction engineering, manufacturing all kinds of metal components bearing static load and unimportant mechanical parts and heat treatment of p355gh general weldments that do not need heat treatment.

Special boiler steel is derived from carbon structural steel, heat treatment of p355gh. The expression of boiler steel grade is similar to that of high-quality carbon structural steel, and the carbon content is usually 0.20%. The chemical composition of boiler steel is basically the same as that of high-quality carbon structural steel of the same brand, but the mechanical properties are strictly required, especially the impact toughness, and the aging sensitivity is required to be small. After deoxidation and removal of non-metallic inclusions, boiler steel has a uniform structure, the grain size is controlled at 3-7 grade, and the defects such as interlayer, shrinkage, porosity and porosity are relatively less.

Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter heat treatment of p355gh steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.

Hot rolled heat treatment of p355gh product stock size: 12*1600*91000, 25*1950*10250, 25*1950*10150, 14*2000*10000, 12*1600*10000, 16*1500*9340, 60*2020*6100, 25*1950*9700, 14*2000*13500, 75*2390*4320, 16*1500*9340, 50*2740*13460, 20*2100*10700, 20*2500*6200, 60*1750*9100, 34*1900*12000, 12*2050*5100, 45*2010*10000, 25*2100*8650, 70*2270*7600, 16*1500*9340, 6*1950*10000, 30*2000*7630, 20*2100*11600, 70*2260*7950, 34*1900*12000.

Our company regularly visits customers, consults and follows up the after-sales service, and directly solves problems for customers. In the use of our steel materials, whether quality problems or not, the after-sales will help solve the problem as soon as possible. We promise free life-long replacement for any product quality problems. The sound after-sales service system make you free from worries.
