• Hastelloy C22, also known as alloy C22, is a versatile austenitic nickel-chromium-molybdenum-tungsten alloy with enhanced resistance to pitting, crevice corrosion and stress corrosion cracking. The high chromium content provides good resistance to oxidizing media while the molybdenum and tungsten content give good resistance to reducing media. This nickel steel alloy also has excellent resistance to oxidizing aqueous media including wet chlorine and mixtures containing nitric acid or oxidizing acids with chlorine ions. Other corrosives Hastelloy C-22 has resistance to are oxidizing acid chlorides, wet chlorine, formic and acetic acids, ferric and cupric chlorides, sea water, brine and many mixed or contaminated chemical solutions, both organic and inorganic. This nickel alloy also offers optimum resistance to environments where reducing and oxidizing conditions are encountered in process streams. This is beneficial in multi- purpose plants where such upset conditions occur frequently.
• This nickel alloy resists the formation of grain-boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in the as-welded condition.
• Alloy C-22 should not be used in service temperatures above 1250 F due to the formation of detrimental phases which form above this temperature.

We are the main supplier of this product.

Stainless Steel 15-5 is a precipitation hardening martensitic stainless steel. It is used in applications requiring better corrosion resistance and transverse properties compared to other similar martensitic grades. Strength and toughness desired can be altered by temperate range in the heat treatment process.

We are stockists of 31803 duplex alloys in sheet, plate, and bar directly distributed globally from our UK stockholding warehouse, combined with our large capacity cutting capabilities we can meet requirements for many industries.

The following are the properties of 31803:

• Stainless ferritic-austenitic Cr-Ni-Mo steel with nitrogen addition.
• High corrosion resistance, especially against stress corrosion cracking in solutions containing chloride.
• Good strength properties.
• Resistant to intergranular corrosion in the temperature range up to 300C.
• Heat treatment subsequent to welding not necessary.
• Surface condition for optimum corrosion resistance: pickled, heat treated free from scale or machined.
