12KH18N10E Stainless Steel Pipes & Tubes — Russian Metals
INTRODUCTION OF 12KH18N10E
Russian GOST grade 12KH18N10E is an austenitic stainless steel designed for strong corrosion resistance, good high-temperature strength and excellent weldability. Thanks to controlled additions and stabilization, it maintains toughness after welding and in mildly elevated-temperature service. At Russian Metals, we stock and supply precision 12KH18N10E pipes, tubes, sheets and bars with quick dispatch across India.Russian Metals delivers reliable 18KHG alloy steel solutions for prototype, batch, and large-volume production.

Equivalent/Comparable Grades & Standards
GOST: 12KH18N10E / 12Х18Н10Е (variants may be Se or Nb stabilized)
AISI/UNS (nearest families): 304/304L (general chemistry family), 303Se (free-machining Se variant); stabilized service may reference 321/347 families depending on Ti/Nb intent.
EN/DIN: 1.4301 / 1.4305 vicinity (check exact spec/intent)
Note: Exact equivalence depends on the specific variant (selenium or niobium-stabilized). We will match your application to the correct spec at the quotation stage.

Weldability :
without limitations - welding is done without heating and subsequent heat treeting
limited weldability - welding is possible under heating up to 100-120 grade and subsequent heat treeting
hard weldability - obtaining the quality welding needs the additional operations:heating up to 200-300 grade; the heat treeting ia annealing
