21Cr-6Ni-9Mn is a high manganese nitrogen strengthened, austenitic stainless steel. It combines high strength in the annealed condition, excellent resistance to oxidation at high temperatures as well as good resistance to lead oxide and a high level of corrosion resistance at ambient temperatures. The alloy can be fabricated and formed much the same as type 304 and 316, and is readily wieldable. It remains nonmagnetic after severe cold work. Please note that we have a minimum order value of £10,000.

6 Mo (UNS S31254) is a super austenitic stainless steel with a high level of molybdenum and nitrogen, providing high resistance to pitting and crevice corrosion as well as high strength compared with conventional austenitic stainless steels such as 316L. The alloy can provide excellent resistance to stress corrosion cracking allowing tube cold formingand may be used without the necessity to re-anneal at testing up to 120°C. Please note that we have a minimum order value of £10,000.

316Ti (UNS S31635) is a titanium stabilised version of 316 molybdenum-bearing austenitic stainless steel. The 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as 304. They also offer higher creep, stress-rupture and tensile strength at elevated temperature. High carbon Alloy 316 stainless steel can be susceptible to sensitisation, the formation of grain boundary chromium carbides at temperatures between approximately 900 and 1500°F (425 to 815°C) which can result in intergranular corrosion. Resistance to sensitisation is achieved in Alloy 316Ti with titanium additions to stabilise the structure against chromium carbide precipitation, which is the source of sensitisation. This stabilisation is achieved by an intermediate temperature heat treatment, during which the titanium reacts with carbon to form titanium carbides. Please note that we have a minimum order value of £10,000.

Grade 316 is the standard molybdenum-bearing grade, second in overall volume production to 304 amongst the austenitic stainless steels.

Grade 316L, the low carbon version of 316 and has very high immunity from sensitization (grain boundary carbide precipitation). It is extensively used in the oil and gas and chemical industries for its cost effective corrosion resistance and ease of fabrication. There is commonly no appreciable price difference between 316 and 316L stainless steel. The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures. Compared to chromium-nickel austenitic stainless steels, 316L stainless steel offers higher creep, stress to rupture and tensile strength at elevated temperatures. Please note that we have a minimum order value of £10,000.

UNS NO8904, commonly known as 904L, is a low carbon high alloy austenitic stainless steel which is widely used in applications where the corrosion properties of AISI 316L and AISI 317L are not adequate. The addition of copper to this grade gives it corrosion resistant properties superior to the conventional chrome nickel stainless steels, in particular to sulphuric, phosphoric and acetic acids. However, there is limited use with hydrochloric acids. It also has a high resistance to pitting in chloride solutions, a high resistance to both crevice and stress corrosion cracking. Alloy 904L performs better than other austenitic stainless steels due to the higher alloying of nickel and molybdenum. The grade is non-magnetic in all conditions and has excellent formability and weldability. The austenitic structure also gives this grade excellent toughness, even down to cryogenic temperatures. Please note that we have a minimum order value of £10,000.

The Type 316 alloys are more resistant to general corrosion and pitting/crevice corrosion than the conventional chromium-nickel austenitic stainless steels such as Type 304. They also offer higher creep, stress-rupture and tensile strength at elevated temperature. The nitrogen in Type 316LN adds additional resistance to sensitization in some circumstances. The nitrogen content of Type 316LN stainless steel also provides some solid solution hardening, raising its minimum specified yield strength compared to Type 316L stainless steel. Like Types 316 and 316L, the Type 316LN alloy also offers good resistance to general corrosion and pitting/crevice corrosion. Please note that we have a minimum order value of £10,000.

Because of its strength, unique density and corrosion resistance, titanium has found applications in many industries. For high quality tubing products, it’s often a better substance to use than competing materials like stainless steels or super alloys. Titanium tubes are light weight and exceptionally corrosion and heat resistantThe density of titanium is about 60 per cent of that of steel- or nickel-based alloys giving significant weight savings in aerospace structures. The tensile strength is better than that of austenitic or ferritic stainless steels. Titanium is exceptionally corrosion resistant and exceeds the resistance of stainless steels in most environments. The metal is non-magnetic too, and has good heat transfer properties, with a melting point higher than steel alloys. Titanium is easily worked.
