One of the most popular and often used Stainless Steel Grades is 304. The 18 - 8 chromium nickel grade is another name for it that the SS 304 Nut Bolt Manufacturer uses. Type 304 stainless steel fasteners provide an affordable option to other stainless steel in addition to being adaptable. Because stainless steel has strong corrosion resistance qualities against a wide range of both general and localised corrosive media, this grade of fasteners is cost-effective.
Table of Content
SS 304 Bolts And Nuts offer good resistance in mildly oxidising and reducing situations in addition to resisting air corrosion. In its welded state, the SS 304 Bolt exhibits high resistance to intergranular corrosion. The 304 Stainless Steel Nuts have a long working or service life because they are good at resisting these contaminants or corrodents. As a result, they do not need to be changed frequently.
The SS 304 Fasteners are known for their corrosion resistance, but they also offer good toughness and hardness qualities. At cryogenic temperatures, type 304 stainless steel fasteners actually display excellent toughness and strength. Due to the alloy's chromium content, the SS 304 Hex Bolts inherit these characteristics. As one of the top SS 304 Fasteners Manufacturers in India, we are well known.
Stainless Steel 304 Bolts comes in many types like SS 304 Hex Bolts, SS 304 Stud Bolts, AISI 304 Flange bolts, SUS 304 Shoulder bolts, Grade 304 Anchor bolts and s30400 bolt. We at Fasteners online provide genuine and online price of Grade 304 Stainless steel bolts and nuts. Our price is applicable in Qatar, UAE, Malaysia, Indonesia, Singapore, Thailand, Zambia, Azerbaijan including West african countries and Middle East countries.
Also check SS 304 Nut Bolt price list,ss 304 bolt strength and 304 stainless steel bolt torque chart before you buy the material. Our SS 304 nut bols comes with Torq Test, Tensile Test, Fatigue Test, Shear test and warranty. The most important thing to know about SS 304 Bolts are Torque chart, Strength, Shear Strength, Grades, Mechanical properties, Torq chart metric and yield strength. That will help to pick the right material.
