Stainless Steel Tube Bright Annealing

Stainless Steel Tube Bright Annealing
Bright annealing tube

This is more commonly referred to as a Bright Annealing (BA) finish. Material with a No. 1 finish is cold rolled using highly polished rolls in contact with the steel surface. This smooths and brightens the surface.

Different from the tranditional process technique, we don't acid pickling at the last 2 steps, but directly bright annealing at the optimum temperature.

Material stainless steel grades:

Also known as "marine grade" stainless steel due to its increased ability to resist saltwater corrosion compared to type 304. SS316 is often used for building nuclear reprocessing plants.

304/304L Stainless Steel

304 Stainless is a low carbon (0.08% max) version of basic 18-8 also known as 302.

316/316L Stainless Steel

Type 316 is more resistant to atmospheric and other mild environments than Type 304.

310S Stainless Steel

310S Stainless Steel has excellent resistance to oxidation under constant temperatures to 2000°F.

317L Stainless Steel

317L is a molybdenum bearing austenitic chromium nickel steel similar to type 316, except the alloy content in 317L is somewhat higher.

321/321H Stainless Steel

Type 321 is basic type 304 modified by adding titanium in an amount at least 5 times the carbon plus nitrogen contents.

410 Stainless Steel

Type 410 is a martensitic stainless steel which is magnetic, resists corrosion in mild environents and has fairly good ductility.

Duplex 2205 (UNS S31803)

Duplex 2205 (UNS S31803), or Avesta Sheffield 2205 is a ferritic-austenitic stainless steel.

Duplex 2507 (UNS S32750)

Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25% chromium, 4% molybdenum...

SUPER DUPLEX UNS S32760

UNS S32760 is described as a super duplex stainless with a microstructure of 50:50 austenite and ferrite.

The material of the stainless steel round bar is from Jiuli and Baosteel China, we control the quality from the very start. We polished three times to make sure the surface is perfect bright and smooth, and without any deficiency in quality. We have precision equipment to test according to the standard required and PMI test to check the material before delivery.
