Stainless steel duplex stainless steels are achieved with an overall lower alloy content than similar-performing super-austenitic grades, making their use cost-effective for many applications. Duplex grades are characterized into groups based on their alloy content and corrosion resistance. Precipitation hardening stainless steels have corrosion resistance comparable to austenitic varieties, but can be precipitation hardened to even higher strengths than the other martensitic grades. The most common, 17-4PH, uses about 17% chromium and 4% nickel. The designation "CRES" is used in various industries to refer to corrosion-resistant steel. Most mentions of CRES refer to stainless steel, although the correspondence is not absolute, because
Braided stainless steel brake lines Braided stainless steel brake lines Braided stainless steel brake lines (also known as braided stainless steel brake hoses) are flexible hoses fitted to a hydraulic brake system. The intent of braided stainless steel brake lines is to improve brake system effectiveness and longevity as compared to an equivalent system fitted with flexible rubber hoses through near-elimination of hose expansion. The difference in expansion characteristics between rubber and braided stainless steel brake lines is a result of differences in hose construction. Where rubber hoses typically consist of a rubber inner hose wrapped in a textile reinforcement braid then covered in an
