Stainless Steel 304 Flat Welding Flange

Stainless Steel 304 Flat Welding Flange Introduction

Stainless Steel 304 Flat Welding Flange, also known as Flange Sheet or Flange Disc, etc., varies by region in terms of naming.

The 304 flat welding flange is a common material in stainless steel flanges, with a density of 7.93 g/cm3, also known as 18/8 stainless steel in the industry. It features excellent machinability and high toughness, and is widely used in the industrial, furniture decoration, and food industries at high temperatures up to 800 degrees.

Connection Type

First, insert the steel pipe into the inner diameter of the flange and perform a single-sided weld; then, tighten the flange on both sides using bolts.

Production Process

Pure material forging, full forging, high-precision CNC turning, CNC arm drilling.

Advantages of 304 Stainless Steel Flat Weld Flange

Excellent corrosion and thermal resistance, low-temperature strength, and mechanical properties; good for hot working processes such as stamping and bending, without hardening after heat treatment (operating temperature range: -196℃ to 800℃).

2: Corrosion in the atmosphere; in industrial atmospheres or heavily polluted areas, timely cleaning is required to avoid corrosion.

3: Suitable for food processing, storage, and transportation. Features good processing properties and weldability.

Procurement Recommendations

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

2: manufacturers of flanges need to provide material inspection reports and related documents for flat焊接 flanges.

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