Stainless steel 304 is an austenitic stainless steel. It contains high nickel content. Typically between 8 and 10.5% by weight. It contains about 18 to 20% by weight of high chromium. Grade 304 stainless steel has low carbon content. It can minimize the chromium carbide precipitation produced by welding and the sensitivity of the alloy to intergranular corrosion.
The alloy also exhibits excellent toughness, even down to cryogenic temperatures. On the other side of the spectrum, in terms of oxidation resistance. It will continue to show significant scaling.
It is the same as most other austenitic grades. Type 304 can be easily welded using common fusion and resistance methods.

PVC film is one of the most important factor when purchasing stainless steel material. Basically, 3 types of PVC films are typically applied.
PE50/PE80 black and white film
This is the most widely used film, the thickness normally ranges from 50 micron to 80 microns. There will not be any special function except protection.,
Laser Film(Novacel 4228)
Laser cutting is often applied as a downstream processing. Laser film is a film that can undertake high temperature. If clients apply the wrong pvc, after laser cutting, the pvc will be wrinkled and sticky to the surface.
Transparent Film
There are normally 2 types of blue transparent film, one is the for deep drawing, another one is normal protection film.
Coil Weight Control
Based on client requirement, we can control the stainless steel coil weight to 1-24 tons.
Coil Package
Every coil has to be packed with stronger steel strip and make sure the wooden pallet is strong enough
Loading and locating
Strengthen steel ropes will be applied to make sure the coils will not move during the loading.
Wooden blocks
To get rid of pallet shift during the transportation, wooden blocks will be applied
Eye to door loading
This loading method is easier for clients to get coils unload.
Complicated loading
This loading method is mainly used for special shipping lines or clients who has a high requirement for shipment.
