ASTM A350 LF2 & SS 316 Blind Flanges Order from Kyrgyz Customer

Views: 158     Author: Site Editor     Publish Time: 2022-12-12      Origin: Site

The customer send inquiry about grilled bind flanges in ANSI/ASME B16.5 ASTM A350 LF2 / A182 F316L , after replying them with quotation,they didn’t have any comment on it during the first several weeks .


However, they kept asking me some question about orders which is not ours, like: I consulted other suppliers about ANSI/ASME B16.5 ASTM A350 LF2 Flanges ,why couldn't they offer me quotation....Because we also manufacture the items they have question with, I confirmed these questions with our factory and solved their queries.In the end, I get several purchase orders from the customer.

ANSI/ASME B16.5 ASTM A182 GRADE F316

A182 F316 /F316L ASME B16.5 Flange composition & Mechanical Properties

F316/316L is the most commonly used austenitic stainless steel in the chemical process industry. The addition of molybdenum increases general corrosion resistance, improves chloride pitting resistance and strengthens the alloy in high temperature service. Through the controlled addition of nitrogen it is common for 316/316L to meet the mechanical properties of 316 straight grade, while maintaining a low carbon content.Flanges in material A350 LF2 is better than it is in A182 F316/316L in every term.
