what is astm b677 specification?
ASTM B677 is a ASTM International standard specification that covers seamless, cold-worked or hot-finished nickel alloy pipe and tube intended for general corrosive service. It defines the requirements for materials designated by various UNS numbers, such as UNS N08904 (904L Stainless Steel), UNS N08925, and UNS N08926, which offer enhanced resistance to corrosion due to their specific alloy composition.
GNEE is one of the renowned distributors, exporters, manufacturers, stockists, and suppliers of high-quality 904 stainless steel seamless pipes. Its products are designed in compliance with international and national raw material quality standards.
ASTM B677 TP 904L stainless steel seamless pipe is a high-alloy, low-carbon austenitic stainless steel pipe manufactured in accordance with the ASTM B677 standard, widely used in applications where the corrosion resistance of 316L and 317L is insufficient. With higher alloy content of nickel and molybdenum, SS 904 seamless pipes deliver superior performance compared to other austenitic stainless steels.
ASTM B677 TP 904L pipes produced under this specification can be manufactured using seamless, hot-worked, or cold-worked methods. Typically, pipes made from ASTM B677 UNS N08904 grade are designed for general corrosion service. Additionally, we supply solution-treated SS 904L pipes, which are quenched in water or rapidly cooled by other methods after heat treatment.
