The important role of nm400 material in life
In 2019, the output of pig iron in the world was 1.265 billion tons, with China accounting for 64%; the overseas output accounted for 36% (460 million tons), ranking 86.982 million tons of EU 28 countries, 74.907 million tons of Japan, 74.099 million tons of India, 73.264 million tons of CIS, and NM400 material 47.521 million tons of South Korea. In the first quarter, the global output was 311 million tons, with a year-on-year decrease of 0.5%, with China NM400 material increasing by 2.4%; the overseas output decreased by 5.4%, Among them, EU decreased by 9.2%, Japan increased by 1.3%, India decreased by 7.7%, CIS increased by 2.1%, and South Korea decreased by 4%.
Our company will set up a full-time service engineer for the project, who is responsible for the interface and coordination of technical support and after-sales service of the NM400 material project. In response process of customer service center, in case of technical support and after-sales service demand, the user shall contact the full-time engineer of NM400 material customer service center, and the technical personnel will give corresponding answers and on-site treatment according to the needs of users.
What is the difference between Q235 steel and Q345 steel? First, strength difference: the lower limit of yield strength of Q235 steel is 235MPA, and the lower limit of yield strength of Q345 steel is 345MPA (Q means "Qu" in Chinese characters, and the later value represents the lower limit of yield strength). Second, the chemical difference: the alloy content of Q235 steel and Q345 steel is different, Q235 steel is ordinary carbon steel, while Q345 steel is low alloy steel NM400 material.
The chemical composition of 20CrMo steel pipe is 0.17-0.24, Si: 0.17-0.37, Mn: 0.40-0.70, Cr: 0.80-1.10, Mo: 0.15-0.25. Mechanical properties of 20CrMo steel pipe: tensile strength 410 Mpa; yield strength: 265mpa; elongation after fracture: 24; reduction of area: 60; impact absorption energy: 110J. 20CrMo steel pipe belongs to alloy structure steel pipe, which has high thermal strength, good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance at 500-520℃. NM400 material, 20CrMo steel pipe is generally used in quenching and tempering state.
In 2015 , We get the tender from Myanmar Government, the total quantity is 1200 ton ABS-AH36 steel plate, we supply the steel plate with painting ( which standard is according to ISO SA2.5) with gray Color 20 Micron. After Get Customer Contract, Steel Plate Are Produced within 25 days .Then, Goods transported to Tianjin Port And Shipping On Time To Statisfy With Project Expected After Finished Producing. The Steel Quality NM400 material we offered receive good Praise from our Customers .
We have replenish steel materials stocks, now there are huge stocks of S355JR, A36, NM400 material A572 Gr 50, 16Mo3, A516 Gr 70, ABS grade A, AH32, AH36, EH36, SPA-H, SG295,SM700C etc steel materials. We can arrange delivery for those stock steel products within short time. Meanwhile, we also provide further processing for the NM400 material steel materials, such as cutting, drilling, bending, welding, etc. Please do not hesitate to contact us if you have any steel demands.
