304 316 High Precision Seamless Precision Stainless Steel Pipe

Product Overview:

TORICH is a professional manfucaturer of hight precision stainless steel tubes. Our high precision stainless steel tubes 

with good processing performance and high toughness, which are widely used in industry, furniture decoration industry

and food and medical industry.

TORICH high precision stainless tube is usually produced based on the following technical standard and grade:

Standards: ASTM A269, ASTM A213,ASTM A312,ASTM A789,ASTM A790 or similar technical standard.

Technique: seamless or welded

Steel Grade:304,304l,316, 316L, or other steel grade upon agreement with customer

304 ------ 18 / 8 stainless steel. The GB brand is 0Cr18Ni9. 309-304 has better temperature resistance than 304.

316 ------ the second most widely used steel after 304, which is mainly used in food industry, pharmaceutical

               industry and surgical equipment. Adding molybdenum makes it obtain a special corrosion-resistant

               structure. Compared with 304 stainless steel pipe, it has better chloride corrosion resistance, so it is

               also used as "marine steel". SS316 is usually used in nuclear fuel recovery units. Grade 18 / 10

               stainless steel pipes generally also meet this application grade.

Surface condition:

Bright Annealed / Polished / Annealed&Pickled / Bright Annealed+Fine polishing / Electropolishing

Application:

Electric heater fields like metal tube heater,hot runner,thermostat,heating apparatus,air conditioning,

refrigerators and other household appliances,heating etc. Food and beverage,petroleum chemical

industry,heat exchanger,condenser,marine environment,paper making,chemical fertilizer,instrumentation,

medical,Automotive engineering,aerospace,pipe structure,priting textile and etc.

Advantage:

Sophisticated bright annealing technology makes the tube good mechanical performance,the tube can

be flared,flatten,bent freely.
