ASTM A193 b8m stud bolt are available in both machined and forged.
Machined- in this process fist the raw material is to be selected and then it is processed through various machine-controlled process which includes CNC machining, heat treatment, surface finishing, thread rolling, coating and inspection and after all these processes the final product stud bolt is ready.Machined process delivers products with high accuracy and precision. This method also provides durability, high strength and smooth surface finish to the SA 193 Gr b8m studs.
Hot forging method-this method involves the deformation of the bolt head by inducing heat followed by recrystallization of the metal temperature and then bend it to obtain the required specific shape and size of Stud A193 b8m.
This process has several other steps which includes uncoiling, straightening, cutting and cold forging. Hot forging process provides strong heat application and mechanical properties to the materials.
SA 193 Gr B8M threaded rod manufacturer in India
Thread rolling process which is a cold forming method uses a collection of hardened steel dies to make threads on the SA 193 Gr B8M studs.
The rolling dies which are used in this process are optically ground and cold form the thread over a pre-machined blank which leads to the formation of virtually perfect threads on Stud bolt b8m with high accuracy and pitch.
This thread rolling studs are far superior than traditional cut threads in terms of strength and mechanical properties.
We are the most affordable supplier of ASTM A193 grade B8M studs and threaded studs in Mumbai in UNF, UNC & Extra Fine UNEF threads

There are various methods to measure stud A193 b8m head size and length:
Analyse the diameter and pitch or thread count of the stud in which the diameter is referred as the width of the stud and thread count or pitch is actually the number of threads per inch.Utilizing a ruler to calculate the distance along the edge of the stud.Using of calliper or measuring tape to measure the length of the stud from end to end.
We are the certified stockholder of SA 193 B8M welded stud bolt and fully threaded studs as quickly as possible with all essential documentation

There are various advantages for which the heat-treated method is applied on A193 gr 8m threaded Bar:
Heat treatment process provides higher creep property to the threaded bar along with better stress to rupture.
This method also provides higher tensile strength to the material.
This process also induces strong high temperature application in the threaded bar.
