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 steel brake lines are typically only seen on upmarket motor vehicles such as hot-rods and supercars, or on race-prepped vehicles such as those used in Formula One and touring car series. Braided stainless steel brake lines are a common aftermarket upgrade, purchased and installed after a vehicle is initially purchased. 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
