316LN (UNS S31653) is a low-carbon, nitrogen-enhanced version of Type 316 molybdenum-bearing austenitic stainless steel. 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.

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.

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. Please note that we have a minimum order value of £10,000.

The welding process is one of the core ways in which we manufacture precision tubes. Our high-quality tubing starts off as a flat strip of metal. The strip is formed into a tube through a series of rollers and the join, also called the seam, is then welded together. Welded Processes Special non-destructive testing methods – including eddy current, ultrasonic and pressure testing - are used to ensure a consistent weld. Just like with seamless manufacturing, welded tubes can be drawn down by plug drawing or sinking. This method can be used to create very long lengths of coiled tube, these can also be measured during coiling using a laser measurement. The main welded tube manufacturing processes used are strip welding and cold drawing, but other important processes in between, or at the end of the drawing process, include Please note that we have a minimum order value of £10,000.

The microstructures inside duplex stainless steels are approximately 50 per cent austenite and 50 per cent ferrite, and consequently duplex products share the physical properties of both ferritic and austenitic grades. Duplex stainless steels are resistant to the cracking caused by chloride stress corrosion in austenitic grades, and have improved resistance to localised corrosion. This family of stainless steels has roughly twice the yield strength of their counterpart austenitic grades . Higher hardness values provide better wear resistance for high precision tubes. Duplex stainless steel tubes have high hardness and wear resistance propertiesDuplex steels are easily welded and formed, similar to austenitic grades. Depending on chromium, nickel and molybdenum content, duplex stainless steels are divided into four main categories: lean duplex, duplex, super duplex and hyper duplex.

The fabrication of Alloy 825 is typical of nickel-base alloys, with material being readily formable and weldable by a variety of techniques Please note that we have a minimum order value of £10,000.

Alloy 800, 800H, and 800HT are nickel-iron-chromium alloys with good strength and excellent resistance to oxidation and carburization in high-temperature exposure.

Alloy 800 was the first of these alloys and it was slightly modified into Alloy 800H. This modification was to control carbon (.05-.10%) and grain size to optimize stress rupture properties. In heat treatment applications Alloy 800HT has further modifications to the combined titanium and aluminium levels (.85-1.20%) to ensure optimum high temperature properties. Alloy 800H/HT was intended for high temperature structural applications.

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.

Surgical Implant 316L is a double melted stainless steel, regarded as a medical grade, this stainless steel is melted to achieve high levels of purity and cleanliness. It has excellent resistance to both general and intergranular corrosion, and pitting and crevice corrosion. The double melting allows for superior surface finish. Surgical implant 316L Stainless Steel is our most commonly sold medical stainless steel. Beyond removing impurities, this process, in combination with the unique nickel and chromium content of 316, tends to facilitate the formation of the surface chromium oxide layer that makes stainless steel corrosion resistant. There is some belief that surgical implant 316L forms a more substantial surface layer, and that this plays a strong role in protecting the host body from reactions to the nickel content of the material.
