Stainless Steel 316 Flange

Product features

Performance dimension 316 flange data vs 304 flange Verification method

1. Strong Cl- tolerance, 316 flange at 60℃, 10000ppm, four times higher than 304 flange

2. Long electrolytic corrosion, experiments show that the pitting equivalent PREN protection is as high as 28.5

3. High thermal fatigue life, in the thermal shock test infrared video, stainless steel 316 flange 10,000 hot and cold cycles

4. High stress corrosion threshold, can be used in 80℃ seawater environment

5. Strong tolerance to sulfuric acid, chemical projects last for 5 years, no corrosion and deformation in 20% H₂SO₄ 50℃ environment

Longan product core value

1. Marine engineering

2. Material authenticity guarantee

Spark spectrum analysis report is provided for each batch, which can be verified by scanning the code with a mobile phone

3. Chemical corrosion terminator

In phosphoric acid scenarios, due to the fluoride ion wet acid of 316, the life is extended by 8 times compared with 304. In 99.5% CH₃COOH and 120℃ environment, the corrosion rate is only 0.002mm/year

4. Failure warning service: Free access to Corrosion Monitoring SaaS, which can monitor the corrosion rate of stainless steel 316 flanges in real time

FAQ

Q: Can it be used in nuclear power plants?

A: It has passed ASME III nuclear power certification, see certificate No. NQA1-316-2024

Q: Is it applicable in high temperature environment?

A: Molybdenum element improves thermal stability, and the continuous working temperature can reach 800℃

Q: How to choose with 316L?

A: Choose 316L (carbon content ≤ 0.03%) for welding scenarios, and stainless steel 316 flanges for non-welding parts are more cost-effective
