TP304/304L Seamless Stainless Steel Tubes For Pharmaceutical Equipment

Specifications: 

After 304, 316 is the most common stainless steel on the market. Again it is an austenitic
grade with the addition of 2 - 3% molybdenum which further improves corrosion resistance. It
is often referred to as a marine grade stainless steel because of its effective resistance to
chloride corrosion in comparison to other stainless steel grades.

The material has superior welding and forming qualities. Grade 316 will require post - weld
annealing to promote maximum corrosion resistance, though this is not necessary if Type
316L is used.

Origins from the Paper Industry

The steel was initially produced for the paper producing industry as it has been shown to be
highly resistant to the sulphur compounds used in paper processing.
Typical applications for this material are now widespread due to its superior corrosion resistance properties when compared to Grade 304.

Type 316 stainless can be found in heat exchangers, pharmaceutical equipment, dairies and breweries, marine
fittings, coastal architectural fascia and fittings and in food preparation areas.

Product Range
316 & 316L steel plate and pipes have common properties and are often stocked with Dual Certification, where it is determined that both have properties and composition which comply with both steel types.
Type 316H is excluded from this scenario by virtue of the fact that unlike 316 & 316L, 316H is engineered to work in elevated
working temperatures.

Background of 316 Stainless Steel Pipes & Tubes
Grade 316 is the standard molybdenum - bearing grade, second in importance to 304 amongst the austenitic stainless steels. The molybdenum gives 316 better overall corrosion resistant properties than Grade 304, particularly higher resistance to pitting and crevice corrosion in chloride environments. It has excellent forming and welding characteristics. It is readily brake or roll formed into a variety of parts for applications in the industrial, architectural, and transportation fields.

Grade 316 also has outstanding welding characteristics. Post - weld annealing is not required when welding thin sections.
Grade 316L, the low carbon version of 316 and is immune from sensitisation (grain boundary carbide precipitation). Thus it is extensively used in heavy gauge welded components (over about 6mm). Grade 316H, with its higher carbon content has
application at elevated temperatures, as does stabilized grade 316Ti.
The austenitic structure also gives these grades excellent toughness, even down to cryogenic temperatures.
