기술ASTM A262 and ASTM A763 detect intergranular attack in austenitic and ferritic stainless steels respectively. Learn which practice to specify, how to write RFQs, and what to check on test reports.
기술Selecting between ASTM A1084 and A923 for lean duplex fittings requires matching the standard to the alloy. Learn what to specify in your RFQ, how to verify test reports, and how to avoid common acceptance mistakes.
기술Duplex fittings require two distinct metallurgical checks: ferrite volume fraction by ASTM E562 and detrimental intermetallic phase detection by ASTM A923. Procurement buyers need to understand the difference before specifying.
기술Macroetch per ASTM E340 helps reveal weld penetration, cracks, and HAZ features. Learn how it fits into ASME Section IX qualification, what to verify, and RFQ inputs for buyers.
기술Learn how ASTM E1077 and A960/A960M apply to decarburization depth on heat-treated fittings, and what to specify in your RFQ to avoid disputes.
기술Grain size testing under ASTM A182 is mandatory only for certain grades. Learn when ASTM E112 applies, which methods are used, and what buyers must verify before accepting a fitting.
기술Charpy impact records for pipe fittings often include subsize specimens. Learn what ASTM E23 and A370 actually require, and where acceptance criteria must be found.
기술Weld repair acceptance for A234 and other wrought steel fittings is governed by the product specification, A960/A960M common requirements, and the purchase order — not by a generic visual pass/fail rule. Here's what to verify.
기술ASTM A960 sets common requirements for wrought steel pipe fittings covered by individual ASTM product specs like A234. This guide explains what buyers must verify when ordering and inspecting fittings.
