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.
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.
Stainless Steel - Grade 304 (UNS S30400)
Fe, <0.08% C, 17.5-20% Cr, 8-11% Ni, <2% Mn, <1% Si, <0.045% P, <0.03%
Grade 304 is the standard "18/8" stainless; it is the most versatile and most widely used stainless steel, available in a wider range of products, forms and finishes than any other. It has excellent forming and welding characteristics. The balanced austenitic structure of Grade 304 enables it to be severely deep drawn without intermediate annealing, which has made this grade dominant in the manufacture of drawn stainless parts such as sinks, hollow-ware and saucepans. For these applications it is common to use special "304DDQ" (Deep Drawing Quality) variants. Grade 304 is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. Grade 304 also has outstanding welding characteristics. Post-weld annealing is not required when welding thin sections.
Grade 304L, the low carbon version of 304, does not require post-weld annealing and so is extensively used in heavy gauge components (over about 6mm). Grade 304H with its higher carbon content finds application at elevated temperatures. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.
These properties are specified for flat rolled product (plate, sheet and coil) in ASTM A240/A240M. Similar but not necessarily identical properties are specified for other products such as pipe and bar in their respective specifications.
Typical compositional ranges for grade 304 stainless steels are given in table 1.

304H also has a requirement for a grain size of ASTM No 7 or coarser.
