Frequently Asked Questions
A2-70 (SS304) is ideal for general corrosion resistance in most environments, while A4-80 (SS316) contains molybdenum for superior resistance to chlorides and marine environments.
They are very similar; ISO 4032 is the international equivalent of the German DIN 934 standard for hexagonal nuts, ensuring global compatibility.
Yes, SS304 maintains good structural integrity at elevated temperatures compared to standard carbon steel, though specific limits depend on the load.
We recommend using a molybdenum-based anti-seize lubricant to prevent cold welding (galling) during the tightening process.
Yes, SS304 is widely used in the food and beverage industry due to its hygienic properties and resistance to organic acids.
Absolutely. We provide full Mill Test Certificates (MTC) ensuring the chemical composition and mechanical properties meet A2-70 standards.
