Stainless Steel 310 Buttweld Fittings

Stainless Steel 310 Reducer is a mixture of several metals (this is called an alloy) but most of it is iron, which is harder and stronger than iron. Stainless Steel 310S Cross Butt Weld Pipe Fittings are often iron alloys with between 0.02 % and 1.7 % percent carbon by weight. Stainless Steel 310 Bend Butt Weld Pipe Fittings with more carbon than this are known as cast iron, in which carbon is replaced with other alloying materials.

Stainless Steel 310S Stub End is different from wrought iron that has little or no carbon, where variations and combinations of production routes also exist. Stainless Steel 310 End Cap Butt Weld Pipe Fittings is an alloy of iron and carbon containing less than 2 % carbon and 1 % manganese and small amounts of silicon, phosphorus, Sulphur and oxygen.
