It shows minimum elongations at elevated temperatures, best for heating equipment fittings.
Specifications and testing
ASTM, ASME, DIN, JS are some standards of SS fasteners. These are manufactured by advanced tools and machines, posses’ precise dimensions and surface finish.

Go with different quality inspection test like the positive material test, intergranular corrosion test, flattening test, flaring test or inspected by third parties. Stainless Steel DIN 1.4319 fasteners come at most reasonable prices, you can buy for quality engineering works. Pack in wooden boxes for preventing damages.
