hardox 400 vs ar400 elements content

15CrMo alloy plate is a pearlite structure heat-resistant steel, which has high thermal strength (δb≥440MPa) and oxidation resistance at high temperature, and HARDOX 400 vs ar400 has certain hydrogen corrosion resistance. Due to the high content of Cr, C and other alloy elements in 15CrMo alloy plate, the steel has obvious hardening tendency and poor weldability. The weight calculation formula of 15CrMo alloy plate: length × width × thickness × 0.00785 = kg / m. Delivery status of 15CrMo alloy plate: hot rolling, controlled rolling, normalizing, high temperature tempering, QT, etc.The company adopts modern management concept, adheres to “quality for survival, integrity for development”, and provides customers with high-quality and reliable steel HARDOX 400 vs ar400 products and wholehearted service. The company continuously deepens the internal reform of the enterprise, innovates in the reform, develops in the innovation, and gradually forms a set of management and operation mechanism which adapts to the HARDOX 400 vs ar400 market and has strong competitiveness."Mirror" refers to the surface state of HARDOX 400 vs ar400 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.After a certain period of time, the steel products will reduce the toughness and increase the hardness, which is called aging effect. Generally, this effect is strongest at 200-300 ℃. The aging tendency of HARDOX 400 vs ar400, low carbon steel (about 0.1% carbon content) is especially large, while high carbon steel and alloy steel containing molybdenum, barium or tungsten are not easy to produce aging. For boiler steel plate, it is required that the reduction rate of impact initial property is not more than 50%, or the absolute value of impact initial property is not less than 3-3.5KGM / cm2.As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality HARDOX 400 vs ar400 products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
