309S Stainless steel plate
The surface of the stainless steel plate is smooth, has high plasticity, toughness and mechanical strength, and is resistant to acid, alkaline gas, solution and other media corrosion. It is an alloy steel that is not easy to rust, but it is not absolutely rust free. Stainless steel plate refers to the steel plate that is resistant to the corrosion of weak media such as atmosphere, steam and water, while the acid-resistant steel plate refers to the steel plate that is resistant to the corrosion of chemical etched media such as acid, alkali and salt. Stainless steel plate since the beginning of the 20th century, has a history of more than 1 century.
309 Stainless steel sheet Price in China ,Manufacturer of 309 Stainless Steel sheet
The 309 is mainly used in cold working condition for equipment parts that bear high loads and want to reduce the weight of the equipment and do not rust.
In addition, this steel is easy to produce work hardening when impacted by external forces and can absorb more impact energy, which will provide a more reliable safety guarantee for equipment and personnel.
The 309 is prone to work hardening during deformation and is used in places requiring higher strength
This is the most cost effective grade of steel. So the 309 Stainless Steel Sheet Price is lower compared to other grades of stainless steels and all metallic products in general. There are different versions of the material with low carbon and high carbon content. The low carbon version, 309 sheets are very good for welding applications as they have less carbide precipitation and less localized corrosion.

309 Characteristic machining technology
1D -- The surface has discontinuous granular shape, also known as fog surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2D - A slightly silvery white colour.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling.
2B -- Silver white with better gloss and flatness than a 2D surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + quenching and tempering rolling.
Ba - Excellent surface gloss, high reflectivity, like a mirror surface.
Processing technology: hot rolling + annealing shot peening pickling + cold rolling + annealing pickling + surface polishing + quenching and tempering rolling.
No.3 -- Good gloss, coarse grain surface.
Processing technology: polishing and tempering rolling for 2D or 2B with 100~120 abrasive materials (JIS R6002).
No.4 -- Good gloss, fine lines on the surface.
Processing process: polishing and tempering rolling for 2D or 2B with 150~180 abrasive materials (JIS R6002).
HL -- Silver grey with hair streaks.
Processing technology: 2D products or 2B products with appropriate granularity of abrasive materials for polishing the surface is a continuous abrasive grain.
MIRRO -- Specular.
Processing technology: 2D products or 2B products with appropriate granularity of the grinding material grinding and polishing to the mirror effect.
