GOST 9941-81 12X18H10T 12X18H12T 08X18H10T 08X18H12T 08Х22Н6Т Seamless Stainless Steel Tube Corrosion Resistant Stainless Steel Tube

Seamless stainless-steel tubes are widely utilized in industries requiring high corrosion resistance and mechanical energy. consistent with the GOST 9941-eighty one wellknown, several chrome steel grades which includes 12X18H10T, 12X18H12T, 08X18H10T, 08X18H12T, and 08Х22Н6Т are commonly synthetic into seamless tubes for various applications.

Material

These stainless steel tubes are primarily austenitic stainless steels with managed additions of nitrogen, titanium, molybdenum, and different alloying elements relying at the grade. The nominal compositions are designed for exceptional corrosion resistance, warmness resistance, and mechanical houses.

Specification

The GOST 9941-81 wellknown specifies the seamless stainless-steel tubes’ dimensions, manufacturing technology, exceptional requirements, and testing methods. The tubes are used for seamless warm-rolled and cold-drawn merchandise with tight dimensional tolerances.

Key Features

• Exceptional corrosion resistance to oxidizing and mildly lowering environments
  Excessive tensile power and sturdiness at room and elevated temperatures
• Good weldability and formability
• Resistance to intergranular corrosion due to controlled titanium stabilization in grades containing 'T'
• Suitable for high-temperature and cryogenic applications (depending on grade)

Chemical Composition

Mechanical Properties

Steel Grade

• 12X18H10T (12Х18Н10Т): Austenitic stainless steel with titanium stabilization for corrosion resistance and heat resistance.
  12X18H12T (12Х18Н12Т): just like 12X18H10T but with better nickel content for improved toughness.
• 08X18H10T (08Х18Н10Т): Lower carbon variant with titanium stabilization.
• 08X18H12T (08Х18Н12Т): Lower carbon and higher nickel with titanium stabilization.
• 08Х22Н6Т: Higher chromium and nitrogen content with titanium; used for enhanced corrosion resistance and strength at high temperatures.

Application

• Chemical and petrochemical industry pipelines and equipment
• Food processing and pharmaceutical industry
• Power plants, boilers, and heat exchangers
• Cryogenic and high-temperature environment tubing
• Architectural and structural components requiring corrosion resistance
• Marine equipment exposed to saline environments
