hardox 400 vs ar400 steel number
Based on the advantages of HARDOX 400 vs ar400 steel resources in domestic market and good reputation, combining with the huge international market demand for steel products, our company started the international business in 2010 and successfully being approved and certified by ISO9001:2008, the Registration number is 626014Q11531R0S. With the quality steel HARDOX 400 vs ar400 products and professional service, our company was award the international acclaim from infrastructure, shipbuilding, petroleum industry etc., and gradually grow into a bright star in the steel export industry .
HARDOX 400 vs ar400, Q195 and Q235 belong to carbon structural steel, which are mainly used in buildings and engineering structures such as workshops, bridges, ships, etc. Of course, there are many differences between Q195 steel and Q235 steel. 1. Different components. The chemical composition of Q195 steel: C ≤ 0.12, Si ≤ 0.30, Mn ≤ 0.50, P ≤ 0.035, S ≤ 0.040. The chemical composition of Q235 steel: C ≤ 0.22, Si ≤ 0.35, Mn ≤ 1.40, P ≤ 0.045, S ≤ 0.050. 2. The prices of HARDOX 400 vs ar400, Q235 steel is higher than that of Q195 steel. 3. The mechanical properties of Q195 and Q235 steel are different. The tensile strength of Q195 steel is ≥390 MPa, yield strength is ≥195 MPa, and the elongation is ≥ 30%. The tensile strength of Q235 steel is 490 MPa, yield strength is ≥235 MPa, and the elongation is 23%.
The surface of alloy steel coil is specially treated during processing. The wear resistance of steel coil and plate made of alloy steel is much better than that of traditional rolling plate, and the cost is also low. The heat resistance and high temperature resistance of alloy steel coil is better than that of traditional rolling plate, and it will not deform easily. Besides, the strength of the HARDOX 400 vs ar400, alloy steel is very high, it is not easy to break and can be used for a long time.
As the thickness and hardness of HARDOX 400 vs ar400 increase, the tendency to crack at the cutting edge increases. In order to prevent the HARDOX 400 vs ar400 from cutting cracks, preheating should be carried out before HARDOX 400 vs ar400 cutting. Special attention should be paid to preheating to make the entire HARDOX 400 vs ar400 interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole HARDOX 400 vs ar400 cannot be preheated, the partial preheating method can be used instead.
HARDOX 400 vs ar400, Low alloy steel plate is a general designation, mainly refers to the steel plate with alloy content less than 3.5%. Alloy steel in the market is distinguished by the total amount of alloy elements, mainly including low alloy steel, medium alloy steel and high alloy steel. When the total alloy amount is less than 3.5%, it is called low alloy steel; if the total alloy amount is 5-10%, it is medium alloy steel; and when the total alloy amount is more than 10%, it is high alloy steel.
We are willing to cooperate sincerely with you with high-quality HARDOX 400 vs ar400 products and sincere service to expand the market and create brilliant! We will work hard to create a first-class steel company and provide you with faster and more considerate after-sales services! Moreover, our shipbuilding steel plates have been certified by the nine countries' classification societies including DNV, ABC, GL, LR, BV, CCS, RINA, NK, and KR. The quality assurance system has passed ISO9001-2000 standard certification.
