Stainless Steel Castings
The standard 304 and 316 type stainless steels offer similar strengths to those of the low carbon steels but with much improved corrosion resistance. The molybdenum containing 316 type has become the standard stainless for constructional applications and sea water environments.
Significantly higher strengths and wear resistance, with lower corrosion resistance, are provided by the 13% chromium and 13/4 (13% chrome with 4% nickel addition) types of stainless steel. The 13/4 type is more commonly employed as a casting over the straight 13% chrome because of its higher ductility and lower propensity to cracking. The 13/4 steel is ideal for many pump parts, particularly impellers where its combination of corrosion and wear resistance, and strength are recognised.
