SUS 303 Peeled Round Bar (JIS G4303) φ35mm x 3,000mm(L)

303 STAINLESS STEEL BAR

303 (UNS 30300) stainless steel bars were developed for machining. Type 303 has a higher concentration of sulfur reducing the drag on cutting tools. It allows greater machining speeds and lower production costs. The alloy is useful whenever a need arises for good corrosion resistance and considerable machining is required.

Austenitic steels have austenite as their primary phase (face centered cubic crystal). These are alloys containing chromium and nickel (sometimes manganese and nitrogen), structured around the Type 302 composition of iron, 18% chromium, and 8% nickel. Austenitic steels are not hardenable by heat treatment. The most familiar stainless steel is probably Type 304, sometimes called T304 or simply 304. Type 304 surgical stainless steel is austenitic steel containing 18-20% chromium and 8-10% nickel.

WELDING CHARACTERISTICS

Not generally recommended, but may be welded with some difficulty
May be welded with Alloy 310 electrodes
Should be annealed after welding to re-dissolve precipitated carbides

MACHINABILITY

High machining rates can be obtained in the annealed condition with hardness in the range of 200 to 240 Brinell
Will work harden, therefore, it should be machined at reduced surface feet per minute and heavier feeds to prevent glazing at the tool interface.
