What is 347 stainless steel?

347 stainless steel is a high-carbon niobium-containing Cr-Ni austenitic stainless steel. Due to the stabilizing element Nb, it has good resistance to intergranular corrosion and polysulfic acid intergranular stress corrosion. Corrosion is similar to 18-8 austenitic stainless steel containing Ti, so it is widely used in boiler, power generation, petroleum, chemical, synthetic fiber, food, paper and other industries. Superheater tubes, reheater tubes, steam pipes and petrochemical heat exchangers for large boilers.

Datasheet

Surface

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.
