The material

Carbon steel (WCB), LCB (low temperature carbon steel), LC3 (3.5% nickel steel), WC5 (1.25% 0.5% chrome molybdenum steel), WC9 chromium (2.25%), C5 (0.5% 5% chromium molybdenum), C12 (9% 1% chromium molybdenum), CA6NM (4 (12% chromium steel), CA15 (4) (12% chromium), CF8M (3 16 stainless steel), CF8C(347 stainless steel), CF8(304 stainless steel), CF3(304L stainless steel), CF3M(316L stainless steel), CN7M(alloy steel), M35-1(Monel), N7M(Hastert nickel alloy B), CW6M(Hastert nickel alloy C), CY40(Inke nickel alloy), etc.

Production technology is mainly divided into forging, casting, cutting, rolling these four.

Cast and forged flanges

The flange cast out, the blank shape and size is accurate, the processing amount is small, the cost is low, but there are casting defects (pores. Crack. Inclusion); Poor streamlining of the internal structure of the casting (even worse if it is a cutting part);

Forged flange is generally lower carbon content than cast flange is not easy to rust, forging streamlined, compact structure, mechanical properties are better than cast flange; .
