Our company is a large NM400 steel grade steel enterprise integrating steel plate production, sales and processing. It is a first-class agent of Shanxi Taigang, Shanghai Baosteel, Jiugang, Xi'an Huaxin, Taishan steel, Dongfang special NM400 steel grade steel and southwest special steel. It is a special dealer of famous steel plants in China, such as Columbus, NAS, acerinox, Outokumpu, Arcelor, nipponmetalindustry, nipponyakinkogyo, NSC, etc.
API 5L is a specification for pipeline steel pipe formulated by the American Petroleum Institute. The main steel grades in API 5L are: A, B, X42, X46, X52, X56, X60, X65, X70, X80, X90, X100, X120, etc. In API standard, pipeline steels are divided into PSL1 and PSL2. In the standard, there are slight differences in chemical composition, NM400 steel grade mechanical properties, inspection items, acceptance standards, delivery status, etc between PSL1 and PSL2 steel. For example, API 5L PSL1 X42 requires an upper carbon limit of 0.26, while API 5L PSL2 X42 requires an upper carbon limit of 0.24.
The NM400 steel grade processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the NM400 steel grade steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.
Welding is mainly used for manufacturing metal structure parts, and also for manufacturing machine parts. The welding connection performance is good, and it is convenient to weld NM400 steel grade steel plates, profiles or castings and forgings according to the needs. At the same time, welding can also connect different shapes and sizes (plate thickness, pipe diameter) or even different materials, so as to reduce weight, save materials, optimize resources and other purposes. The welding structure has high rigidity, good integrity, and easy to ensure air tightness and water tightness, so it is especially suitable for NM400 steel grade manufacturing hollow structures with high strength and large rigidity (such as pressure vessels, pipes, boilers, etc.).
"ASTM A516 Grade 70 plate is a boiler / pressure vessel quality of steel plate for use in low to moderate services. It has improved notch toughness. NM400 steel grade, A516 Grade 70 steel plates can be produced with thick up to 200mm.For boiler steel plate A516 Grade 70, the yield strength shall be above 260 Mpa, tensile strength from 485 Mpa to 620 Mpa.A516 Garde70 steel plate is equivalent to the P355GH and 490B grades. "
Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel NM400 steel grade plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
