Stainless Steel 304 Flange

Material characteristics

1. High fatigue strength. Through servo hydraulic test, Stainless Steel 304 Flange is 15% higher than carbon steel (16.2W/m·K)

2. High intergranular corrosion threshold. In the metallographic atlas database, sensitization at 650℃ for 0.5h still passes the ASTM A262-E test

3. Long tolerance to Cl- ions. It can last for five years in an environment of 2000ppm @ 60℃.

4. Thermal conductivity advantage. Through third-party thermal imaging comparison, Stainless Steel 304 Flange is 15% higher than carbon steel (16.2W/m·K) "

5. Strong welding HAZ hardness. The common microhardness scan shows ≤220 HV

Longan product application

1. Food and pharmaceutical industry

2. Energy industry

Stress corrosion: Pre-cooling processing technology improves SCC threshold by 37%, and passed NACE TM0177 certification.

Offshore platform: The North Sea project has been in service for 8 years, and the pitting depth is <0.05mm

3. Cost control evidence

The logistics damage rate is only 0.22%, and the inventory turnover rate can reach 15 days, which is a full 30 days lower than the industry average.

Global application evidence:

Failure probability: Based on 100,000 pieces of Stainless Steel 304 Flange monitoring data, there are only 0.0003 times/year·piece

Currently, the global real-time project map shows 1,565 running devices
