Our focus is on providing customers with high end steels that are not rolled or stocked locally. Grade L, the low carbon version of and is immune from sensitisation grain boundary carbide precipitation. Thus it is extensively used in heavy gauge welded components over about 6mm. There is commonly no appreciable price difference between and L stainless steel. For this reason low speeds and constant feed rates are recommended.
Approved Lab. Urgent order also accepted. We have a full range of expertise for Export Packing. If required we arrange for packaging also for sea freight , supply plastic caps or protection rings at the pipe ends and organise special marking. Stainless Steel L Seamless tube may be furnished bare or coated and with capped ends. In order to prevent rust during sea shipment, bundles of Stainless Steel L Seamless tube may be wrapped with polypropylene sheets, and secured with flat steel bands. Our stock range consists of the following:.
Nominal Pipe Size inches. Victor Steel can polish nearly any stainless steel pipe item to a 4 polish, 6 Polish, 7 polish or a 8 mirror finish. Stainless steel polished pipes can also be cut to size. Victor Steel can hone pipe and tube, using a precision abrasion process in order to obtain a desired finish or close dimensional tolerance. Some grades of stainless steel pipe and tube can be heatreated to change the mechanical properties.
In some cases, secondary annealing series stainless steel may be required depending on the application. Victor Steel can perform PMI testing in house for most stainless steel grades, or we can work with independent labs to complete PMI in order to meet customer specifications. In some cases, UT testing of the stainless steel pipe and tueb may be required.
We can assist you with this requirement. Outside Diameter.
ASTM A269 Seamless Tubing
ASTM standards organization develops and approvals technical standards, to improve materials, products, systems, and services requirements. ASTM A welded tubes are for boiler, super heater, heat exchanger, condenser system, the pressure equipment is used to transfer heat. ASTM A tubing is for general service, usually, it is applied in equipment and instruments, also under low or high temperature environment, therefore, ASTM A tubing is also used for heat transfer equipment. However, in some cases, Ferritic and Duplex steel tubes are produced to comply with A or A standard, Ferritic steel tubes can reduce cost, and duplex steel tubes increase strength and longevity. ASTM A indicate welded tubes, the tubes should be cold worked or cold drawn method, prior to final heat treatment.
304/304L Stainless Steel Tubing
ASTM A Stainless Steel tube provides the best resistance to pitting and corrosion of any of the austenitic series stainless steels. It is extremely ductile, with excellent strength at elevated temperatures. It is ideal for hydraulic and instrumentation tubing in chemical, textile, and pulp and paper industries, and in marine environments. Different mechanical test requirements that include, flange test, flaring test, hardness test, and reverse flattening test are presented. The ASME SA specification covers nominal wall thickness, welded and seamless austenitic steel tubing for general corrosion-resisting and low- or high-temperature service. Upon completion, all material shall:.
