Stainless Steel
A steel alloy known as stainless steel has a minimum of 10.5% chromium with varying amounts of nickel, molybdenum, and niobium.
Stainless steel is more resistant to oxidation, rust, and corrosion than ordinary steel. Calico Metal Industries offers stainless steel in a wide variety of shapes, grades, finishes, gauges, widths, and lengths. Stainless steel is used in many various industries, such as manufacturing, oil & gas, aerospace, and automotive, among many others. Please give us a call or get in touch if you are unable to locate the precise kind of stainless steel you are searching for.
Type 304 :
The most common grade is the classic 18/8 stainless steel. Also referred to as “A2” in accordance with International Organization for Standardization ISO 3506.

Type 310S :
Type 310S is a low carbon austenitic stainless steel. Known for its ability to withstand high temperature applications, Type 310S, which is a lower carbon version of Type 310, also offers users an array of benefits including:
● Outstanding corrosion resistance
● Good aqueous corrosion resistance
● Not prone to thermal fatigue and cyclic heating
● Superior to Type 304 and 309 in most environments
● Good strength in temperatures up to 2100°F
Type 316L:
The second most common grade (after 304); for food and surgical stainless steel uses; Alloy addition of molybdenum prevents specific forms of corrosion. Also known as “marine grade” stainless steel due to its increased resistance to chloride corrosion compared to type 304. SS316 is often used for building nuclear reprocessing plants. Most watches that are made of stainless steel are made of this grade. Rolex is an exception in that they use Type 904L. 18/10 stainless often corresponds to this grade. Also referred to as “A4” in accordance with International Organization for Standardization ISO 3506.
Type 321:
The second most common grade (after 304); for food and surgical stainless steel uses; Alloy addition of molybdenum prevents specific forms of corrosion. Also known as “marine grade” stainless steel due to its increased resistance to chloride corrosion compared to type 304. SS316 is often used for building nuclear reprocessing plants. Most watches that are made of stainless steel are made of this grade. Rolex is an exception in that they use Type 904L. 18/10 stainless often corresponds to this grade. Also referred to as “A4” in accordance with International Organization for Standardization ISO 3506.
Type 321H:
Type 321H, is a titanium stabilized austenitic stainless steel that is known for its general corrosion resistance. This higher carbon version of Type 321 stainless steel offers a wide variety of benefits including
● Excellent resistance oxidation to 1500°F (816°C)
● Good low temperature toughness
● Comparable corrosion resistance and machinability to Type 304
● Readily welded by most standard processes
● Very ductile and forms easily
Type 904L :
Type 904L is a high alloy austenitic stainless steel that is known for its corrosion properties. This low carbon version of Type 904 stainless steel also offers other benefits to users including
SMO 254 :
Alloy 254, which is also found under the brand name Sandvik 254 SMO and UNS S31254, is a super austenitic stainless steel that is well known for its outstanding resistance to pitting, crevice corrosion, stress cracking, and fatigue corrosion. One reason for these unique properties is Alloy 254’s specific chemical make-up that includes
● Fe (remainder)
● Cr 19.5-20.5%
● Ni 17.5-18.5%
● Mo 6-6.5%
● Mn 1.0% max
● Si 0.8% max
● P 0.03% max
● C 0.02% max
Alloy 20 :
Specifically designed to withstand sulfuric acid Alloy 20 offers excellent corrosion resistance. Due to its nickel, chromium, molybdenum and copper levels Alloy 20 is ideal for use in corrosive environments. At 33% nickel, Alloy 20 has practical immunity to chloride stress corrosion cracking. This alloy is often chosen to solve stress corrosion cracking problems, which may occur with 316L stainless.
● Sulfuric acid pickling tanks, racks and heating coils
● Phosphate coating drums and racks
● Heat exchangers
● Bubble caps
● Process piping
● Mixing tanks
● Chemical and petroleum process equipment
Type 430 :
Decorative, e.g., for automotive trim; ferritic. Good formability, but with reduced temperature and corrosion resistance.
Type 17-4 PH :
17-4 PH, also known as UNS S17400, is a martensitic precipitation-hardening stainless steel. 17-4 PH is popular with our customers due to its excellent combination of good corrosion resistance and high strength. In order to be considered 17-4 PH, an alloy must be made of a unique set of chemical elements:
● Fe Balance
● Cr 15-17%
● Ni 3-5%
● Cu 3-5%
● Mn 1.5% max
● Si 0.7% max
● Nb 0.45% max
Type 15-5 PH
15-5 PH, also known as also known as UNS S15500 or XM-12,is a martensitic, precipitation hardening stainless steel. Popular due to its high strength and good corrosion resistance, 15-5 PH also offers user a host of other benefits:
● Good mechanical properties at temperatures up to 600°F (316°C)
● Excellent longitudinal and transverse toughness
● Good in corrosive and high-pressure environments
● Equivalent weldability to 17-4 PH with greater toughness
● Low temperature hardening
