Hot-rolled coil has relatively low strength, poor surface quality (low
oxidation/smoothness), but good plasticity, generally medium and
heavy plate, cold-rolled sheet: high strength, high hardness, high
surface finish, generally thin sheet, can be used as stamping With
the board.
Hot-rolled steel sheet, mechanical properties are far less than
cold processing, second only to forging, but with good toughness
and ductility

Welding
Excellent weldability by all standard fusion and resistance
methods, both with and without filler metals. Heavy welded sections
in Grade 201 require post-weld annealing for maximum corrosion
resistance.
Machining
Stainless steel tends to work harden if machined too quickly. For
this reason low speeds and constant feed rates are recommended.
Factory and Machinery Equipment :
We had our own factory to do slitting re-rolling and finish
treatment machine,PVC and interleaving paper we will using with our
machine for you,could protect stainless steel surface from damage
or any scratches,
1. CNC Flame Cutting Machine
2. CNC Plasma Cutting Machine
3. CNC Laser Cutting Machine
4. Bending Machine
5. Shearing Machine
6. Punch Machine
7. Driving Machine
Packing
waterproof paper and steel strip reinforcement,one package about 2
tons,Load in 20GP / 40GP
Inspection :
Factory supply inspection before shipment,sampling test( cut one
piece for you to test in our lab or some other lab like SGS TUV
which you trust )
you also could inspection of loading on the forwarder warehouse or
our Mill.
