When to paint hardox 400 weight calculator
At the same time of doing well in HARDOX 400 weight calculator production and operation, Yunnan company focused on completing the four phases of technical transformation construction projects, realizing industrial upgrading, improving equipment level, and laying a good foundation for the future development of the company. In the HARDOX 400 weight calculator technological transformation project, pollution control facilities have been built synchronously, and a large number of comprehensive utilization projects, such as comprehensive sewage treatment and recycling project, blast furnace gas waste heat and residual pressure power generation, have been invested and constructed.
S50C steel plate is a high-quality high-quality medium carbon steel. S stands for steel, which means iron, and 50 stands for carbon content of 0.50%. C represents carbon steel, which means that S50C is a carbon steel with a carbon content of 0.50%.Mechanical properties of S50C steel plate:Tensile strength σb (MPa): ≥630 (64); Yield strength σs (MPa): ≥375 (38); Elongation δ5 (%): ≥14; Reduction of area ψ (%): ≥40; Impact Work Akv (J): ≥31(4); Impact toughness value αkv (J/cm2): ≥39(4)Hardness: unheated, ≤241HB; annealed steel, ≤207HB
Weathering steel is characterized in that the alloy composition and weight percentage content. The chemical composition C≤0.12, Si: 0.25 ~ 0.75, Mn: 0.20 ~ 0.50, P: 0.07 ~ 0.15, S≤0.03, Cu: 0.25 ~ 0.55 , Cr: 0.30 ~ 1.25, Ni≤0.65, and the rest are Fe and trace impurities. Weathering steel sheet HARDOX 400 weight calculator is mainly used for steel structures such as railways, vehicles, bridges, and towers that are exposed to the atmosphere for a long time.
"Mirror" refers to the surface state of HARDOX 400 weight calculator stainless steel, which is usually 8K in the industry. The common mirror stainless steel on the market is divided into 6K, 8K and 10K, which are general polishing, 6K, 8K fine grinding and 10K super fine grinding effect. The same thickness generally has no big difference, 10K mirror is brighter; the thicker the thickness, the better the effect, and the higher the processing cost.
What is the difference between Q345B steel and Q345A steel? HARDOX 400 weight calculator, Q345B steel and Q345A steel have slight difference in chemical composition: Q345A steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.045, S ≤ 0.045, V 0.02 ~ 0.15; Q345B steel: C ≤ 0.20, Mn ≤ 1.7, Si ≤ 0.55, P ≤ 0.040, S ≤ 0.040, V 0.02 ~ 0.15. The difference between Q345B steel and Q345A steel is mainly in A and B behind the steel grade, Q345A steel grade is not subject to impact; Q345B steel grade needs 20 ℃ room temperature impact test.
If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
