The company has always adhered to the principle of "genuine goods at low prices", put an end to the sale of fake and shoddy P235GH boiler steel process products, do not deceive customers, treat customers in good faith, truly consider for customers and give advice. To provide reference opinions, and to treat customers with integrity. Consequently, we have won a lot of p235gh boiler steel process stable cooperated customers over the years in the international market. Our steel materials are widely used in power stations, bridges, ship manufacturing, offshore platforms, heavy machinery, oil and gas pipelines, tanks and so on fields.

A387Gr91 plate is a chromium-molybdenum alloy steel. It has the functions of hydrogen embrittlement, hydrogen corrosion, hydrogen stripping, and sulfide corrosion in a hydrogen environment at medium temperature (350-480 ℃). It also has good low tempering brittleness. p235gh boiler steel process, A387Gr91 alloy steel is widely used in the manufacture of chemical fertilizers, petrochemicals, and thermal power plant equipment, such as synthetic ammonia reactors, coal gasifiers, shift furnaces, and hydrogenation reactors.

X56 steel plate is a kind of steel mainly used for large-diameter pipelines. API X56 steel plate is used to manufacture buried pipelines for natural gas transmission. Due to the corrosion of soil, serious degradation will occur. The corrosion type of X56 steel plate that can be produced is usually general corrosion and pitting. we are API 5L X56 steel suppliers ,we also can supply API 5L X52,API 5L X60,API 5L X65,API 5L X70,API 5L X80,please contact us if you need.

Composition characteristics of low alloy structural steel, p235gh boiler steel process: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.

p235gh boiler steel process, S355JR is a European standard low alloy high strength structural steel, which is in accordance with EN10025-2. The hardness of S355JR steel is 70-80B, and the yield strength of S355JR steel is 355MPa. JR stands for quality level, equivalent to level B in ChinaChemical composition of S355JR steel: C: < 0.22; Si: < 0.55; Mn: < 1.60; P: < 0.025; S: < 0.025S355JR steel is equivalent to Q345B in China.
