316 stainless steel coil is part of the austenitic family of stainless steel. 316 grades contain a higher level of Nickel than 304 giving it an improved corrosion resistance over 304 grades. 316 sheet possesses excellent mechanical properties at sub-zero temperatures and good corrosion resistance making it a great choice for marine applications.

Applications:

• Chemical
• Marine
• Petrochemical
• Machined parts

Product Details:

Stainless steels are high-alloy steels which have high corrosion resistance compared to other steels due to the presence of large amounts of chromium. Based on their crystalline structure, they are divided into three types such as ferritic, austenitic, and martensitic steels. Another group of stainless steels is precipitation-hardened steels. They are a combination of martensitic and austenitic steels.

Details:

• Tempering in the range 425-565 DegreeC is to be avoided because of reduced impact resistance and corrosion resistance.
• Tempering in the range 590-675 DegreeC results in lower hardness (the product become machinable) and high impact resistance.

The proper hot work range is 2000 to 2200 DegreeF (1093 to 1204 DegreeC):

• Do not work this material below 1650oF (899 DegreeC)
• Readily welded by all standard methods
• To reduce the risk of cracking, it is suggested to pre-heat the work piece to 350 to 400 DegreeF (177 to 204 DegreeC)
• Post weld annealing is recommended to retain maximum ductility

Stainless Steel 321 Coil Corrosion Resistance:

• Exhibits good general corrosion resistance that is comparable to 304.
• Developed for use in the chromium carbide precipitation range of 1800 – 1500°f (427 – 816°c).
• Can be used in most diluted organic acids at moderate temperatures.
• Can be used in pure phosphoric acid at lower temperatures.
• Can be used in up to 10% diluted solutions at elevated temperatures.
• Resists polythionic acid stress corrosion cracking in hydrocarbon service.
• Utilized in chloride or fluoride free caustic solutions at moderate temperatures.
• Does not perform well in chloride solutions, even in small concentrations, or in sulfuric acid service.

Type 201 Stainless Steel is an austenitic chromium-nickel-manganese stainless steel which was developed to conserve nickel. Type 201 is a lower cost alternative to conventional Cr-Ni stainless steels such as 301 and 304. Nickel is replaced by additions of manganese and nitrogen. It is non-hardenable by thermal treatment but may be cold worked to high tensile strengths. Type 201 is essentially nonmagnetic in the annealed condition and becomes magnetic when cold worked. Type 201 can be substituted for Type 301 in many applications

Stainless Steel 201 Coil Product Forms:
Typical applications for Types 201 are cookware, hose clamps, piston rings, transit car structural member, transit car roofing/siding, thermal window spacers, airbag containers, and truck trailer posts and door frames.The annealing temperature for Type 201 is between 1850-2000 DegreeF. Rapid cooling through the carbide precipitation range (1500 - 800 o F) is necessary to keep the carbides in solution and prevent sensitization. Type 201 is not hardenable by thermal treatment; it is only hardenable by cold working.Type 201 has similar bending, forming and drawing characteristics to Type 301 stainless steel

Good oxidation resistance in intermittent service to 870O C and in continuous service to 920O C:

• Continuous use of Alloy 304 in the 425-860°C range is not recommended if subsequent aqueous corrosion resistance is important
• Alloy 304H has higher strength at elevated temperatures so is often used for structural and pressure-containing applications at temperatures above about 500°C and up to about 800°C
• Alloy 304H will become sensitized in the temperature range of 425-860°C; this is not a problem for high-temperature applications but will result in reduced aqueous corrosion.
