The main technical and economic indicators still needs further improvement, our hot-rolled finished steel (billet - wood) finished product rate at about 93%, of which hot-rolled seamless steel Pipes (billets - material) finished product rate, depending on their level of technical equipment of different volatility large, technologically advanced mills typically 90-92%; the technology behind the mill is only about 80%; 75% or more advanced rolling mills, behind the mill is 70% or less. In short, these indicators compared with the international advanced level there is still a gap, needs to be improved. Stainless Steel Pipes from excellent performance point of view, it is a safe, reliable, health and environmental protection, affordable, easy to use and fast, with other pipe irreplaceable advantages, construction of more and more applications, stainless steel car axis maintenance, use will become increasingly popular, stainless steel car axis, prospects. Therefore, to improve the competitiveness of the stainless steel Pipes, we must improve the production technology, while addressing the source of the problem embryo material, the only way to make the steel industry to go further. Features stainless steel cord heat treatment: stainless steel heat treatment is to change its physical properties, mechanical properties, residual stress and recovery due to the pre-processing and heat severely affected by corrosion resistance in order to obtain optimum performance stainless steel or stainless steel to be able to further cold and hot processing. Austenitic stainless steel is a special steel, nickel steel, high chromium content, due to the presence of nickel, chromium and other alloying elements, the treatment of ordinary steel heat treatment does not have the characteristics of: 1) heating temperature than high, stainless steel car axis, the heating time is relatively long. 2) The low thermal conductivity of stainless steel, Stainless steel car axis, at low temperature uniformity is poor. 3) control the furnace atmosphere is very important to prevent carburizing, nitriding and decarbonization and peroxide phenomenon. 4) surface gloss stainless steel have a decisive impact on the use of the product and the price, iron oxide produced during the heat treatment, it will seriously affect the surface gloss.
