Stainless Steel Pipes & Tubes
Product Overview
R V Metal Corporation supplies a complete range of stainless steel pipes and tubes across a wide spectrum of austenitic, ferritic, martensitic and duplex grades to match real project conditions—not generic “one-grade-fits-all” supply. Our portfolio covers cost-optimized 200-series options such as J4, J7, 201 and 202 for decorative and light-duty fabrication; work-hardening and spring applications in 301/302; and the industry-standard 304 family (304/304L/304H/305) for general corrosion resistance, forming and food-grade utility. For higher temperature and oxidation environments we offer 309/309S and 310/310S, while Mo-bearing 316/316L/316H/316Ti and 317/317L grades are available for chloride exposure, chemical service and marine-adjacent installations. Stabilized grades like 321/321H and 347/347H are supplied for weld-heavy jobs and elevated-temperature piping where carbide precipitation resistance matters. For heat-tolerant and magnetic ferritic applications we stock 409L, 429, 430, 430Ti, 439, 441 and 444—widely used in exhaust systems, heat exchangers and corrosion-resistance-with-lower-Ni requirements—along with martensitic grades 410/410S and 420 for wear, strength and hardenable components. For higher strength and superior chloride stress corrosion resistance, Duplex S31803 is offered for aggressive industrial and marine service. Pipes and tubes can be supplied as welded or seamless (as applicable), in mill finish or polished finishes, with tight dimensional control, test certificates (MTC), and project-specific compliance to ASTM/EN/IS requirements as required by consultants, OEMs and EPC contractors.
