Versatile Overseas is a branded trader of SS 310 / 310S Fasteners, which are strong in production and make sure to give long service life. ASTM A193 Stainless Steel 310 Fasteners offers a greater carbon content, for to deliver best quality of rising temperature potency.

ASME SA193 Stainless Steel 310S Fasteners is a stabilised alloy that provides as its prime benefit an outstanding resistance to inter granular corrosion. Alloy 310 Socket Set Screws offers exposure to temperatures in the chromium carbide precipitation that ranges from 427 Deg Celsius to 816 Deg Celsius. Grade 310 Lock Nuts is a lower carbon form which offers resistance to sensitisation throughout welding and other thermal procedures. Type 310 U Bolts are recognized as superior-alloy steels and contain around 4 percent to 30 percent of chromium. AISI 310 Sealing Washers is a superiornickel, molybdenum and chromium form that is considered mainly for increased corrosion resistance and strength.Due to the higher designing and superior grade industrial procedures, our 310S Stainless Steel Anchore Screws are immensely commended among our customers. UNS S31000 Eye Nuts is lengthily used in the chemical along with oil and gas industries, for its reasonableease of fabrication and corrosion resistance.


UNS S31635 Eye Bolts is the lower carbon form and is resistant from sensitization (grain boundary carbide precipitation). WNR. 1.4841 Split Washers is a collection of austenitic alloys by means of having greater corrosion resistance.
