POPULAR STAINLESS STEEL GRADES: SS 304 | SS 410 | SS 316 | 17-4
We has experience pouring a wide variety of stainless steel alloy casts. We cast stainless steel from miniature to 50 pounds.
The most common alloys we have poured are listed below. We are also capable of pouring other air melt alloys upon your request. Specific material chemistry and mechanical specifications will be provided to you if needed. For your Stainless Steel Castings needs, we can help you out.
Commonly Cast Stainless Steel Alloys:
Stainless Steel 304(1.4308)
This is the most common stainless steel and is applied in different applications. It consists of at least 18% chromium and 8% nickel and has no magnetic properties within its austenitic structure.
Stainless Steel 304L(1.4309)
Corresponds to stainless steel 304. The ‘L’ stands for ‘low carbon’, so this stainless steel has a lower carbon amount to increase weldability and to limit the corrosion sensitivity after welding.
Stainless Steel 316(1.4408)
A better, but more expensive type of corrosion resistant steel is stainless steel 316. This alloy contains at least 16% chromium, 10% nickel and 2% molybdenum. Because of the addition of molybdenum, this stainless steel type is better defended against salt corrosion and acids, and is often applied in chemical industries.
Stainless Steel 316L(1.4409)
Comparable to stainless steel 316 but with a lower carbon level to increase weldability of the stainless steel.
17-4 PH(1.4549)
A high quality stainless steel which is regularly used in the aircraft industry. It is characterized by a high tensile strength, hardness, toughness and is also corrosion resistant.
