All You Need to Know About Precipitation Hardening Stainless Steel X2CrTiNb18, 1.4509 According to EN 10088-3


What is 1.4509 Stainless Steel Grade

In comparison to 1.4016 / X6Cr17 materials, the 1.4509 grade has much greater pitting, slit, and intergranular corrosion resistance, and its high temperature oxidation resistance is attributable to higher Niobium concentration. Because of its strong corrosion resistance and longevity, this type of stainless steel is widely used.
