409 410 420 Grade Cold Rolled Stainless Steel Plate Sheet 4mm Thickness

What is the difference between 409 and 410 stainless steel?

The corrosion resistance of 409 stainless is about the same as Type 410 stainless steel. Type 409 offers improved corrosion resistance in comparison to carbon steels. However, its corrosion resistance is lower in comparison to other stainless steels with higher chromium content.

What is 409 grade stainless steel?

Alloy 409 is a general purpose, chromium, titanium stabilized, ferritic stainless steel whose primary application is automotive exhaust systems. It contains 11% chromium which is the minimum amount for the formation of the passive surface film which gives stainless steels their corrosion resistance.

Does 409 stainless steel rust?

409 stainless steel is still more rust-resistant than Mild Steel However, neither type of metal is 100% rust-proof. 409 stainless steel can contain up to 90% iron, meaning a magnet will stick to it and is prone to rust.

Stainless Steel Surface / Finish :

No.4	It has good gloss and fine lines on the surface. Processing technology: Polishing and tempering rolling of 2D products or 2B with 150 ~ 180 abrasive material (JIS R6002).
HL	It is silver-gray with hair streaks. Processing technology: Polish the 2D product or 2B product with a suitable size of abrasive material to make the surface appear continuous grain.
8K	It is in a mirror state. Processing technology: 2D or 2B products are ground and polished to a mirror effect with a suitable abrasive material.
2B	It is silvery white and better gloss and flatness than 2D surface. Processing technology: hot rolling + annealing shot peening pickling+ cold rolling + annealing pickling + quenching and tempering rolling.
BA	The surface gloss is excellent and has a high reflectivity, just like the mirror surface. Processing technology: hot rolling +annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenched and tempered rolling.
1D	surface has discontinuous particles, also known as matte. Processing technology: hot rolling + annealing shot peening pickling +cold rolling + annealing pickling.
2D	It is slightly shiny silvery white. Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
No.3	has better gloss and rough surface. Processing technology: Polishing and tempering rolling of 2D products or 2B with 100 ~ 120 abrasive materials (JIS R6002).
SB	The surface is smooth, the texture is clear, the texture is delicate, the appearance is comfortable, and the taste is high-grade.It is widely praised by consumers especially in kitchen appliances.

Packaging: According to customers' needs, use wrapping paper. If the transportation period exceeds 10 days or encounters special climate, we will use waterproof packaging and add plastic film to prevent moisture, water and rust.
Loading: We use the wooden pallet,triangular wood to fix the coil,and the steel wire rope to hold on the both side. That can prevent from the crush injury effectively.
