This is a standard 18/8 austenitic SS grade. These have excellent forming welding properties. The 304L is a down temperature grade does not require the post weld annealing process. These are developed for the heavy gauge applications. It has the austenitic structure provides excellent toughness even in the lower temperatures.

Resistance ability of seamless pipes:
These are pipes are exclusively used in a wide range of atmospheres and many corrosive environments. Stainless Steel 304L Seamless Pipes can be subjected to the pitting and crevice corrosion in the warm surroundings. Also, these can be utilized in stress corrosion cracking media about 50 deg C. It is considered for application in potable water at nominal temperature. Seamless pipes have resistance in cyclic environments service up to 870 deg C and offer continuous service up to 925 deg C. The continuous use of grade is not recommended above to the given temperatures.

However, the lower carbon version will not suffer from this problem. For service above 500 deg C, these pipes are chosen.

The improved machinability version of the grade is available in the round shape of pipes. It significantly better than the standard version of the grade enables higher material removal rate and lowers the tool wear in many operations. The reliability of machining and surface quality will enhanced too. There are machinability experts for optimal set-up for specific machining operations.

Heat treatments:
The temperature ranges are applicable for the manufacturing process is between 900- 1200 deg C. This grade is also subjected to the annealing process between 1010-1120deg C. These are rapidly cooled by metal treatment or annealing process. However, this grade cannot harden by thermal treatment operations.

Weldability:
This grade has excellent weldability by all standard methods such as fusion, arc and resistance welding even with and without filler materials. The heavy section of seamless pipes may be required post weld heat treatments that attain higher corrosion resistance. However, the post weld heat treatment will not be required in the lower carbon version. This pre-qualifies welding treatment.

Why it is chosen instead of its standard grade?
The lower work hardening rate is required for cold forging process, with higher machinability. Good machinability property, lower corrosion rates in the reducing environments. Higher formability, weldability is acceptable. This grade has higher resistance rates to pitting and crevice corrosion resistance in chloride and halide environments. The lower cost is required for reducing erosion and fabrication properties are needed.

The relevant tests are performed by us for quality assurance. The tests begin with crude material testing. The tests include a destructive test and non-destructive test, dimensional tests, flattening test and more.
