Weston Stainless, Midland, UK, is a reputable manufacturer of stainless steel products with high–quality fastening solutions for different industries. One of its most important products, Stainless Steel 436 Fasteners, is a ferritic stainless steel fastener that boasts good corrosion resistance, thermal stability, and excellent machinability. Made of Grade 436 stainless steel, these fasteners come in different shapes like bolts, nuts, screws, washers, and studs and are thus highly versatile. Owing to a higher chromium and molybdenum composition, Stainless Steel 436 Fasteners exhibit impressive resistance to oxidation, stress corrosion cracking, as well as wear and are perfect for harsh industrial uses.
Stainless Steel 436 Fasteners consist of iron, chromium (16.0-18.0%), molybdenum (0.75-1.25%), carbon (0.12% max), manganese (1.0% max), and silicon (1.0% max), providing improved corrosion and oxidation resistance. The fasteners have a tensile strength of around 450 MPa, a yield strength of about 280 MPa, and an elongation of around 22%. With a density of 7.7 g/cm³ and melting point around 1480°C, they have good thermal conductivity and fair hardness between 85-90 HRB. They have excellent mechanical properties, and their durability to withstand long-lasting performance at high temperatures and stresses is assured.

Stainless Steel 436 Fasteners are utilized extensively in automobile, building, and manufacturing industries because they exhibit good resistance against high temperature, corrosion, and oxidation. They are widely used in exhaust systems, heat exchangers, and furnace elements where thermal stability is paramount. They are also used in petrochemical refineries, food processing equipment, and marine vessels because of their resistance to chloride-induced corrosion. Their mechanical strength and durability suit them well to fasten heavy-duty industrial equipment components, allowing for long-term reliability, safety, and efficiency in harsh operating conditions.
Stainless Steel 436 Fasteners include necessary test certificates such as material test reports (MTR), third-party inspection reports, and EN 10204 3.1 certification to meet industry standards. Careful packaging in wooden crates, cartons, or plastic-wrapped bundles to avoid damage in transit ensures delivery of products on time and with reliability, thus ensuring customers have their products in perfect condition, with customized packaging available on demand to suit special industry requirements without compromising product integrity and quality assurance.
