Malzeme 1.4529
Stainless steel
Grade 1.4529 is a stainless super-austenitic nickel-chrome-molybdenum-copper steel with a very low carbon content. By its chemical composition it is highly corrosion resistant in reduced acids. The addition of nitrogen increases the yield strength. It can often be found in the cobstruction industry, especially in the tunnel construction industry as well as in the construction of swimming pool facilities.
