Product Description
310S stainless steel is austenitic chromium-nickel stainless steel, which has good oxidation resistance, corrosion resistance, and high temperature resistance. Because of the higher percentage of chromium and nickel, it has much better creep strength and can continue to work at high temperatures. Has good high temperature resistance. Due to the high content of nickel (Ni) and chromium (Cr), it has good oxidation resistance, corrosion resistance, acid and alkali resistance, and high temperature resistance. High temperature resistant steel pipes are specially used for the manufacture of electric furnace tubes and other occasions. After the content, due to its solid solution strengthening effect to improve the strength, the chemical composition of austenitic stainless steel is based on the addition of molybdenum, tungsten, niobium and titanium based on chromium and nickel. Therefore, it has high strength and creep strength at high temperature. Melting point is 1470 ° C, 800 ° C begins to soften, and allowable stress continues to decrease.

1D—The surface has discontinuous particles, which is also called
matte. Processing technology: hot rolling + annealing shot peening
pickling + cold rolling + annealing pickling.
2D—Slightly shiny silver-white. Processing technology: hot rolling
+ annealing shot peening pickling + cold rolling + annealing
pickling.
2B—Silver 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.
No.3—has better gloss and rough surface. Processing technology:
Polishing and tempering rolling of 2D products or 2B with 100 ~ 120
abrasive materials.
No.4—has better gloss and fine lines on the surface. Processing
technology: Polishing and tempering rolling of 2D products or 2B
with 150 ~ 180 abrasive materials.
HL—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.
MIRROR—is in a mirror state. Processing technology: 2D or 2B
products are ground and polished to a mirror effect with a suitable
abrasive material.
