## Questions & answers
### [What is the difference between 304 and 316 stainless steel pipe?](https://readyscan.ai/entities/shanghai-toko-technology-co-ltd-q141380492#company-answer-content-native-digital-agencies-3f9e45e152f3348a-a-3eb988adf57df35c5881)
“The key difference is molybdenum content. 316/316L contains 2-3% molybdenum, which significantly improves pitting corrosion resistance in chloride-containing environments. 304/304L has no intentional molybdenum addition. For chemical processing, offshore, and coastal applications where chlorides are present, 316L is the minimum recommended grade. 304L is suitable for general industrial, food processing, and architectural applications with low chloride exposure.”

### [What does NACE MR0175 compliance mean for pipe supply?](https://readyscan.ai/entities/shanghai-toko-technology-co-ltd-q141380492#company-answer-content-native-digital-agencies-3f9e45e152f3348a-a-061fd7d64c73d1a93caa)
“NACE MR0175/ISO 15156 specifies material requirements for equipment used in H₂S-containing (sour) environments in oil and gas production. For austenitic stainless steel pipe, NACE compliance means: maximum hardness HRC 22, solution-annealed condition, carbon ≤ 0.03% for L-grades, and no cold work that could increase hardness. TOKO TECH verifies NACE compliance with hardness testing and PMI per tube.”

### [What is PREN and why does it matter?](https://readyscan.ai/entities/shanghai-toko-technology-co-ltd-q141380492#company-answer-content-native-digital-agencies-3f9e45e152f3348a-a-6e20a2220eab098eabee)
“PREN (Pitting Resistance Equivalent Number) = %Cr + 3.3×%Mo + 16×%N. It quantifies a stainless steel's resistance to pitting corrosion in chloride environments.”
