ASTM A193 Grade B16 Fasteners Supplier in Mumbai, India

ASTM A193 Grade B16 is a specification for high-temperature, high-strength alloy steel fasteners. These fasteners are typically used in applications where high tensile strength resistance to corrosion and elevated temperatures are required. Here's some information about ASTM A193 Grade B16 fasteners:

Material Composition: ASTM A193 Grade B16 fasteners are made from chromium-molybdenum-vanadium alloy steel. The chemical composition typically includes chromium, molybdenum, vanadium, carbon, manganese, phosphorus, sulfur, silicon, and sometimes other elements in trace amounts. This composition provides excellent mechanical properties, including high tensile strength and hardness.

Types of Fasteners: ASTM A193 Grade B16 covers various types of fasteners, including bolts, studs, screws, and other externally threaded fasteners. These fasteners come in different shapes and sizes to suit various applications, such as hex bolts, studs with threads on both ends, and socket head cap screws.

ASTM A193 Grade B16 Fasteners Manufacturing Process

Cold Forging

This initial process is a cold forging process used to produce a near net shape work billet. An important consideration in cold forging is the tendency for the bar tobolts Manufacturing Process buckle if its unsupported length to diameter ratio is too high. This ratio usually is limited to less than 4:1 but with suitable dies, therefore, cold forging is the most likely production method because bolts have a large head-to-shank ratio, they are longer than 1½ times their diameter, bolts have multiple diameters and finally require a geometrical shap

Thread rolling

The next process applied to the bottom of the work billet is a bulk deformation process known as "thread rolling". This type of cold-forging process is used bolts Manufacturing Processbecause cylindrical can easily have thread applied by rolling the work billet through two dies. The thread rolling process is usually chosen over machining because thread rolling provides higher production rates, more effective material usage, stronger thread due to work hardening and finally better fatigue resistance because the work billet undergoes compressive stresses during the rolling process.

Blackening and Galvanization

The final process induced on the now almost complete bolt is the application of an anti-corrosive layer, to stop oxidation. The usual process is called "blackening"; Either process chemically or physically coats the surface of ferrous metals, creating a strong barrier against humidity and corrosion. Hot Blackening is most popular & common blackening processes:

Hot Blackening

Hot blackening involves dipping the bolt into six different tanks. The bolt is usually "dipped" by automated part carriers for transportation between tanks. These tanks contain, in order, alkaline cleaner, water, caustic soda at 450°C to 500°C and finally the sealant, which is usually crude oil. The caustic soda bonds chemically to the surface of the metal, creating a porous base layer on the bolt.
