Product Details

Stainless Steel Round Pipe 2 to 4 Inches Thickness Large SS Pipes

304 Stainless steel is the most widely used chromium-nickel stainless steel. As a widely used steel, it has good corrosion resistance, heat resistance, low temperature strength and mechanical properties; it has good hot workability such as stamping and bending without heat treatment Hardening phenomenon (use temperature -196℃～800℃). It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. It is suitable for food processing, storage and transportation. Has good processing properties and weldability.

3. Surface:

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.
