What is the nm500 steel sheet price surface treatment

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of NM500 steel sheet price steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main NM500 steel sheet price production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

The JIS G3106 NM500 steel sheet price specification is a hot-rolled carbon steel plate for welded structures. The NM500 steel sheet price steel grades include: SM400A/B/C, SM490A/B/C, SM490YA/YB, SM520B/C, SM570.

S235JR steel plate is one mainly of Carbon and low alloy steel, S235JR steel plate is a type of steel sheet under EN standard which is used to build ship, bridge, belongs to high strength sheet. EN10025-2 S235JR is equivalent to DIN:ST37-2,JIS:SS400,ASTM:A283C, GB Q235B and UNI:FE360B.

After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of NM500 steel sheet price, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.

NM500 steel sheet price, P355GH plate mechanical properties: P355GH steel plate thickness/mm:> 60-100: tensile strength σb / MPa: 490-630; yield strength σx / MPa:> = 315 Impact absorption energy AKv / J:> = 34. Steel plate thickness / mm:> 100-150: tensile strength σb / MPa: 480-630,y ield strength σx / MPa:> = 295 Impact absorption energy AKv / J:> = 34. Chemical composition % (C:0.10-0.22, Si:<=03.60, Mn:1.00-1.70, Nb:<=0.010, Ti:<=0.03 S:<=0.030, P:<=0.025, Cr:<=0.30, Ni:<=0.30, Cu:<=0.30, Mo:<=0.10, V <=0.02)

It is a modern high-tech professional enterprise integrating scientific research, NM500 steel sheet price production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as NM500 steel sheet price process technology development, technology transfer and related technical consulting and technical services.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
