Core Advantages of 1.5752
It can withstand heavy impact without rupturing, making it perfect for stainless steel fittings in high stress areas. Can ensure reliability in harsh environments such as industrial machinery or aerospace systems.
Hardened to 62 HRC, it prevents wear, scratches and dents on fittings. This not only extends service life but also reduces maintenance costs.
With a tensile strength of 1100 MPa, it keeps stainless steel piping systems solid under pressure. Prevents bending or breaking, providing stability for heavy-duty applications.
Annealed 1.5752 is easy to cut and form, speeding up the production of precision stainless steel fittings. Saves time and reduces costs without compromising quality.
