nm400 material specification and a36 plate specification

Some NM400 material specification, low-alloy high-strength steels have good atmospheric corrosion resistance, which can not only improve the effect of anti-corrosion coatings, but also in some cases take appropriate precautions and even be exposed to the atmosphere without coating. Elements that improve atmospheric corrosion resistance are copper, phosphorus, silicon, chromium, nickel, and molybdenum. The excellent atmospheric corrosion resistance has led to the formation of new concepts for structural design of buildings, bridges, and other structures.

The chemical composition difference between NM400 material specification, Q235B and 20# steel is as follows: The chemical composition of 20# steel: C: 0.17-0.23%, Si: 0.17-0.37%, Mn: 0.35-0.65%, Cr: ≤ 0.25%, Ni: ≤ 0.30%, Cu: ≤ 0.25%. Chemical composition of Q235B steel: C: ≤ 0.20%, Si: ≤ 0.35%, Mn: ≤ 1.40%, P: ≤ 0.045%, S: ≤ 0.045%. The difference of mechanical properties between NM400 material specification, Q235B and 20# steel is as follows: The mechanical properties of 20# steel: tensile strength 410 MPa; yield strength 245 MPa; elongation after fracture: 25; reduction of area: 55; no impact. Q235B steel mechanical properties: tensile strength 370-500 Mpa; yield strength: ≥ 235 Mpa; elongation after fracture: 25; impact absorption energy: 27J.

Management information and high efficiency. Because of the rapid flow of NM400 material specification goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation

When providing technical services on site, the after-sales personnel shall strictly abide by the safety rules and regulations of the construction site, consciously take safety protection measures (such as wearing safety helmet when entering the construction site), accept the supervision and management of the site; without permission on the construction site, they shall not dismantle, smear or damage any goods; the commissioning of contract goods shall be carried out under the supervision of the site supervisor If necessary, it shall be approved by the site supervisor or the person in charge of the project department.

A Uganda client purchased 2100 tons SG255 gas cylinder steel coils in 2018. It is the first company in Uganda to provide re-furbishing, re-certification and manufacturing of new lpg cylinders. They have regular demands for sg255 coils NM400 material specification every 3 months. Limited by inland location, we can only ship container to mombasa, and then transfer to kampala. OurJISG3116 SG255 steel product is grade for gas cylinder steel with the tensile strength of 400MPa and the yield strength of 255MPa.
