1.4550 (X6CrNiNb18-10, AISI 347) and 1.4541 (X6CrNiTi18-10, AISI 321) are niobium- and titanium-stabilized austenitic stainless steels designed to resist intergranular corrosion after welding or servi

1.4550 (AISI 347) is a niobium-stabilized austenitic stainless steel, primarily composed of chromium (17-19%), nickel (9-13%), and niobium (Nb) (at least 10 times the carbon content, up to 1.0%), desi

The EN 1.4550 (X6CrNiNb18-10) stainless steel is equivalent to the AISI 347 (UNS S34700) in the US system, a columbium-stabilized austenitic stainless steel used for elevated temperature service, with

1.4541 (AISI 321) and 1.4301 (AISI 304) are the same 18-10 austenitic family separated by a titanium addition. This article compares composition, equivalents across EN, AISI, JIS, ISO and GB systems,

EN 1.4878 is a titanium-stabilised heat-resisting austenitic grade equivalent to AISI 321H (UNS S32109), designed for creep service at elevated temperature. EN 1.4571 is the molybdenum-bearing, titani

SUS321 is stable in the sensitization temperature range of 400–800℃ and has an oxidation resistance temperature of approximately 900℃. SUS347, due to the higher thermal stability of niobium, can be u

321 Stainless Steel Plate: Welding Techniques Welding SUS321 (Type 321) stainless steel requires the use of appropriate filler material (such as ER347), maintaining cleanliness, and employing TIG/MIG

The main difference between SS 321 and SS 321H is carbon content: 321 has a max of 0.08% C, while 321H has a higher range (0.04-0.10% C), giving it superior high-temperature strength and creep resista

ASTM A240 UNS S32109 refers to Type 321H stainless steel, which is a titanium-stabilized austenitic stainless steel, particularly suitable for high-temperature welding applications. Due to its higher

321 stainless steel is a titanium-stabilized austenitic stainless steel with a composition that includes approximately 17-19% chromium, 9-12% nickel, and a minimum of five times the carbon content in

The main difference is that 1.4878 (AISI 321H) is a higher-carbon version of 1.4541 (AISI 321), while 1.4961 is a different type of alloy based on nickel, not iron like the others.

1.4878 stainless steel (also known as AISI 321H) is a titanium-stabilized austenitic grade with key elements including 17.0-19.0% Chromium (Cr), 9.0-12.0% Nickel (Ni), and a controlled Carbon (C) cont
