Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional S355MC vs s355jr production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of s355mc vs s355jr leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.
As a leading s355mc vs s355jr, S420NL hot rolled plates and sheets supplier, we can supply structural steel S420NL plates up to 250mm. It is often delivered in normalized or normalized rolled condition. When customers need doing the third party inspection for S420NL steel plates,our mill would issue the MTC under format EN10204 3.2, the third party can stamped and report the result on our original MTC when inspection is done completely.
With equipment, technology, production technology, quality supervision and other leading advantages, we are leading in the production of all kinds of high-quality, high-tech medium, extra thick, extra wide steel plate s355mc vs s355jr shaped parts. The cutting surface is smooth and clean, the cutting edge is neat, without secondary processing by users, and it can be installed and used directly according to the technical dimensions, with the characteristics of high coincidence rate of positive and negative tolerance and excellent quality. The processed steel products are mainly used in heavy machinery and equipment.
A small amount of Nb is sufficient to obtain excellent comprehensive properties of s355mc vs s355jr etc. steel material, because at low Nb concentration, the yield strength of steel material increases faster and is proportional to the concentration, but when the Nb content is greater than 0.03%, the strengthening effect begins to decrease. Studies have shown that when the Nb content is greater than 0.06%, excess Nb will no longer strengthen the steel material.
20 # material is a high-quality low-carbon carbon steel, cold-extruded, carburized and hardened steel. s355mc vs s355jr, 20 # material has low strength, good toughness, plasticity and good weldability. Chemical composition of 20 # round steel bar: C: 0.17 ~ 0.23, Si: 0.17 ~ 0.37, Mn: 0.35 ~ 0.65, S: ≤0.035, P: ≤0.035, Cr: ≤0.25, Ni: ≤0.30, Cu: ≤0.25. 20# carbon steel mechanical properties: Shear strength 275 ~ 392MPa, Tensile strength is 253 ~ 500MPa, elongation min. 25%.
The strip steel thickness is generally below 6mm, which is convenient for crimping and processing. You should choose the s355mc vs s355jr, strip steel specifications according to your own purposes. The specifications and materials used for different purposes are different, so you must confirm it before buying. It is best to ask professionals to give advice before purchasing strip steel, and purchase the specifications and types you need according to the corresponding requirements.
