StarBlaze TIG Wire ER308H

STARBLAZE TIG 308H is a premium high-carbon austenitic stainless steel TIG welding rod engineered for precision Gas Tungsten Arc Welding (GTAW).
It complies strictly with the international AWS/SFA A5.9 ER308H classification.
Unlike the extra-low carbon variant (308L), the "H" designation indicates a deliberately higher carbon content. This chemical profiling delivers vastly improved structural strength, high-temperature stable mechanical performance, and superior creep resistance.

Product Overview & Composition
Alloy Classification: Conforms tightly to standard
AWS A5.9: ER308H and EN ISO 14343-A: W 19 9 H.

Chemical Profile: Formulated with a base chemistry of 20% Chromium and 10% Nickel.
Elevated Carbon Window: Formulated with a controlled, high-carbon range (typically 0.04% to 0.08%) to prevent failure, sagging, or softening under extreme heat.
Microstructure: Maintains a balanced ferrite level to minimize hot-cracking tendencies during the cooling phase.

Compatible Base Materials
This filler metal is tailored specifically for high-temperature service steels, including:
AISI 304H and
AISI 308HWerkstoff Nr. 1.4948 (X6CrNi18-10)
