Rail cars, automotive for severe cold heading such as the manufacture of cross recess screws. corrosion resistance at least equivalent to type machining grade .

5 Domestic and mild industrial environment. Water low in chlorides. Nuts and bolts, shafts, fittings. corrosion resistance lower than resistance to corrosion , good for malleability and weldability. Most commonly used storage, laundry and kitchen products, water, food, architectural, cryogenic and hightemperature applications. UGIMA 304 improved machinability bar with same resistance as for 304. Low carbon variation for heavy gauge welded resistance as for 304. High carbon gives improved high temperature resistance to corrosion , particularly attack by hot sulphur compounds in oxidisinggases.

6 Sulphite liquors and acids such as acetic, citric, lactic and nitric. Welding wire for joiningdissimilar corrosion resistance at normal temperatures. Good resistance to oxidisation andcarburising atmospheres in high temperatures over 850 C to 1100 C. Welding wire for joiningdissimilar corrosion resistance to the complex sulphur compounds used in pulp and paper processing. Also resists attack by marine and corrosive industrial atmospheres. Suitable for mildseacoast atmosphere, pulp and paper, heat exchangers, propeller shafts, dying equipment. UGIMA 316 improved machinability bar, with same resistance as for carbon variation, suitable for heavy gauge corrosion resistance over type 316.

7 Often successfully applied where type 316 has given only moderate performance. Applications such as acetic acid distillation, pulp and papermachinery, ink and dying processes. 317L is a variation of 317 suitable for heavy gauge corrosion resistance , equivalent to 304 in the annealed condition and superior if theapplication involves service in 425 C-870 C range. Typical applications include expansion joints,furnace parts, aerospace and power industries, heat exchangers and steam grade is resistant to chromium carbide precipitation. Most commonly found as a consumablefor welding 321.
