AMS5646
COMMON NAMES:
BS S130D
347 Stainless
UNS S34700
FORM & USE:
AMS5646 is a heat and corrosion resistant steel. We hold this grade in round bar form. The material is typically used for parts requiring good corrosion resistance which will be subjected to elevated temperatures during fabrication and service. The material is particularly good for parts requiring oxidation resistance up to 816oC. Material is supplied in the solution heat treated condition.
SIZES STOCKED:
12.7 mm dia – 139.7 mm dia
GENERAL:
Material is premium aircraft-quality conforming to AMS2300.
