JIS G3464 STBL 380 Low Temperature Heat Exchanger Tubes Alloy Steel Seamless Pipe
Material
STBL 380 is a low-temperature alloy steel grade defined under JIS G3464, specifically developed for seamless steel tubes used in heat exchangers, condensers, and similar equipment operating at low temperatures. These tubes offer high toughness, good impact resistance, and reliable performance in cryogenic and sub-zero service conditions.
Specifications
Standard: JIS G3464
Grade: STBL 380
Type: Seamless alloy steel pipe
Application: Heat exchanger and condenser tubes for low-temperature service
Dimensions: As per JIS G3464 (outside diameter, wall thickness, and length can be customized)
