The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, normalised GL-AH 36 heavy steel plate seamless steel pipes for ships and petroleum cracking normalised GL-AH 36 heavy steel plate steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many normalised GL-AH 36 heavy steel plate products have been exported to the Middle East, India, Southeast Asia and Europe and America.
SA516Gr45 (R-HIC) This type of steel plate is mainly used in the manufacture of equipment used in wet hydrogen sulfide environment, such as: liquefied petroleum gas desulfurization system, stable absorption system for catalytic cracking, condensation system of atmospheric and vacuum distillation tower, etc. The material normalised GL-AH 36 heavy steel plate has the characteristics of high purity, low P, low S, good uniformity of structure and mechanical properties, resistance to hydrogen cracking and sulfide stress corrosion.
The difference between Q195 steel and 20# steel: normalised GL-AH 36 heavy steel plate, Q195 steel is ordinary carbon structural steel, in which alloy elements are not specially added, and it is mainly used for construction and engineering structures. Q195 steel has low carbon and manganese content, low strength, good plasticity, high toughness, and good process performance and weldability. 20# steel is high-quality carbon structural steel. Alloy elements are not specially added to 20# steel, and it is mainly used in the manufacture of machine structures, and the amount of use is particularly large. 20# steel has higher strength than Q195 steel, good weldability, no temper brittleness, and its workability can be improved by water quenching.
The purpose of normalised GL-AH 36 heavy steel plate quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of normalised GL-AH 36 heavy steel plate. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.
A131 EH36 steel is high strength marine grade hull structural steel. Its yield strength is no less than 355Mpa, tensile strength is 490-620 Mpa, and elongation is 19% min. normalised GL-AH 36 heavy steel plate, EH36 steel strength is close to S355 steel. However, EH36 steel is shipbuilding steel, while S355 steel is carbon structural steel, and can not be certified by classification society. That is to say, S355 steel is not allowed to be used for ship building when there is certificate requirement. A131 EH36 steel is widely used to build ships working in low temperature water.
Our company will accept the product quality objection registration record, pass it to the normalised GL-AH 36 heavy steel plate production unit and relevant departments, and timely coordinate the supervision of product normalised GL-AH 36 heavy steel plate quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
