Stainless Steel 316L Flat Welding Flange

Stainless Steel 316 Flat Weld Flange Brief Introduction

Stainless steel 316 flat welding flange, also known as flange plate or flange disc, etc., varies by region in terms of naming.

316 welding flange sheet, with added Mo, exhibits excellent corrosion resistance, atmospheric corrosion resistance, and high-temperature strength, suitable for use under severe conditions; possesses good work-hardening properties (non-magnetic); high-temperature strength enhanced; non-magnetic in solution state; cold rolled product with good luster and attractive appearance; relatively more expensive than 304 stainless steel welding flange.

Stainless steel 316 flat welding flange sheet, with the addition of Mo element, significantly improves its corrosion resistance and high-temperature strength. It can withstand temperatures up to 1200-1300 degrees Celsius, making it suitable for use under harsh conditions.

Advantages of 316 Stainless Steel Flat Weld Flanges

1: Stainless Steel 316 flat weld flange, due to the addition of Mo, exhibits excellent corrosion resistance, atmospheric corrosion resistance, and high-temperature strength, making it suitable for use under harsh conditions; possesses good work-hardening properties (non-magnetic); high-temperature strength enhanced; non-magnetic in solution state; cold rolled products have a good luster and look attractive; relatively more expensive than 304 stainless steel.

Stainless Steel 316 flat welding flange sheets, with the addition of Mo element, significantly enhance their corrosion resistance and high-temperature strength. They can withstand temperatures up to 1200-1300 degrees Celsius, making them suitable for use under harsh conditions.

Application: Equipment for use in seawater, chemicals, dyes, papermaking, oxalic acid, fertilizers, etc.; photographic, food industry, coastal facilities, ropes, CD poles, bolts, nuts.

Procurement Recommendations

1: Recommend purchasing from a reputable stainless steel flange manufacturer with a certain production scale.

2: manufacturers of flanges are required to provide material inspection reports and other relevant documents for flat welding flanges.

3: Flat welding flanges must have corresponding specification and model steel stamps and markings.
