Remark |
Understanding how nickel affects the price of stainless steel can be relayed as follows:- T304 has approximately 8% nickel (so 1000 kg of S/S has 80 kg of nickel) T316 has approximately 10% nickel (so 1000 kg of S/S has 100 kg of nickel) Please refer to the London Metal Exchange website http://www.lme.co.uk/nickel.asp for up to date nickel prices. |

Description and General Uses |
304 |
The most widely used stainless steel with the best all round performance. Its carbon content is lower and its corrosion after welding resistance is higher than T302. It is less susceptible to intergranular corrosion after welding. Non magnetic but slightly magnetic when cold worked. |
304L |
A low carbon stainless steel with general corrosion resistance like T304, but with superior resistance to intergranular corrosion following welding or stress relieving. Highly recommended for parts which are fabricated by welding and which can not be annealed. Generally limited to temperatures up to 426°C. The physical properties and thermal treatments of T304L are similar but not identical to T304. Non magnetic when annealed but slightly magnetic when cold worked. |
316 |
Also known as Marine grade stainless steel. T316 has 2-3% Molybdenum which improves corrosion resistance. T316 has superior corrosion resistance to other austenitic steels when exposed to many types of chemical corrodents as well as marine environments -T316 also has applications in the chemical, textile, and paper industries. It has better strength and creep resistance at high temperatures than T304 and greater work hardening properties. Non magnetic but slightly magnetic when cold worked. |
316L |
Has lower carbon than T316, with corrosion resistance similar to T316 but superior resistance to intergranular corrosion following welding or stress relieving. It is recommended for parts which cannot be subsequently annealed. Service temperaturesup to 426°C. The physical properties and thermal treatments of type 316L are similar butnot identical to type 316. Non-magnetic when annealed but slightly magnetic when cold worked. |
310s |
310S has been developed for high temperature service where high creep strength is required. Max service temp is around 1100°C but it is not recommended for applications of prolonged service as it may become brittle. Non magnetic when annealed or cold worked. |
321 |
Basically 302 (basic 18/8) stabilised by the addition of Tanium to five times the carbon content. This prevents intergranular corrosion and offers scale resistance at higher temperatures up to 850°C. Corrosion resistance is lower than 304. Not recommended for bright/mirror polishing. Non-magnetic when annealed but slightly magnetic when cold worked. |
904L |
High resistance to general corrosion, e.g Sulphuric and acetic acids, crevice corrosion, stress corrosion, pitting in chlorine bearing solutions. Good weldability. |
