1.4303 - aisi 305 pipe, wire, circle

Supplier — AvekGlob Company — offers at different prices from the manufacturer various bulk metal products — pipes, wires and wheels made of AISI 305 stainless steel (1.4303). A timely delivery of metal products to any address specified by the customer is guaranteed.

Technical specifications

Stainless steel grade AISI 305 (1.4303) is austenitic grade stainless steel, which is specially designed for the subsequent plastic deformation of the original rolled products into the final product using hot or cold stamping technology. The production of pipes, wire or a circle of steel AISI 305 (1.4303) is conducted in accordance with the technical requirements of the UNS S30500 specification.

The main components of steel AISI 305 (1.4303) are chromium and nickel, and microalloying with niobium gives the material an increased plasticity when forming in the cold state, as well as stabilization of the dimensions of the blanks at elevated temperatures. Simultaneously, due to the very low carbon content, the antimagnetic properties are enhanced, as well as resistance to corrosion and oxidation.

Urgency of application

The main advantage of austenitic stainless steel AISI 305 (1.4303) is an excellent moldability in the cold state, which makes it possible to produce from it constructively complex products without the need for intermediate annealing.

The steel is resistant to solutions of many, halogen-free, organic and inorganic compounds in a wide range of temperatures and concentrations. In aqueous solutions containing halides, for example, chlorides or bromides, pitting corrosion can occur depending on the concentration, temperature, pH and concentration of oxidizing compounds.

Steel AISI 305 (1.4303) can be used indoors and outdoors in rural areas and in urban environments where chloride contamination is relatively small. Typical products that are manufactured from the steel under consideration are industrial parts with complex shapes, operated in corrosive media, rollers of calibration coils of production equipment and other products whose operating temperatures on the surface do not exceed 50 ° C.

Technological features of processing and assortment

Stainless steel AISI 305 or 1.4303 is available in a wide range of rolling profiles and forgings. High plasticity makes it possible to produce products of complex shapes and configurations from this material. The steel is perfectly welded by all the technologies of electric welding, but its gas welding is not recommended because of the appearance of significant shrinkage stresses.

Supplier — AvekGlob company — offers to buy a bar or a circle that are made of AISI 305 or 1.4303 stainless steel at a price formed on the basis of European and world standards of production. Buy these products can be wholesale and retail. For regular customers, there is a flexible system of discounts.
