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 or machine from abrasion, and for an improved appearance. Coated braided stainless steel hoses have the same essential construction as rubber hoses in terms of an inner hose wrapped in a braid followed by an outer layer, but the different materials in the braided stainless steel hoses offer substantially different and arguably better characteristics. To more thoroughly explain why, it is helpful to understand the basics of a hydraulic brake system. The typical operation of a hydraulic brake system uses the premise of fluid displacement to convert operator input into friction. This fluid transfer is accomplished by a connecting tube
