ASTM A193 B7M Bolts

This specification covers fasteners made from chromium-molybdenum stainless steel that undergoes heat treatment. Hilton Steel can supply ASTM A193 B7M bolts in sizes up to 4 inches or higher (4 to 7 inches).
Selecting the right size for your fasteners is imperative for long-term durability.

We advise buyers to consider the bolt shank length, threading, and diameter while choosing ASTM A 193 GR B7M anchor bolts. Other crucial considerations are:

• The amount of load it will withstand
• The environment it will operate in
• The thread pitch of the A193 B7M stud bolt, i.e., the number of threads in an inch or the distance between two adjacent threads

SA 193 grade B7M studs and hex bolts manufacturer in India

These studs are ideal for challenging environments due to their strength and corrosion resistance. An SA 193 B7M stud bolt exhibits a tensile strength of 100 ksi or around 690 MPa. The yield strength is roughly 75 ksi or 517 MPa. However, protective coatings can enhance the metallurgical properties at an additional cost.

Our company can deliver ASTM B7M socket head cap screws with PTFE, xylan, and cadmium coats. Galvanisation (hot-dip) is also a popular option, using zinc to up the corrosion resistance of the component.

If you are looking for B7M material supplier in Mumbai, you are at right place, buy A193 B7M stud bolt in custom sizes

Yes. Since A193 GR B7M hex bolts use AISI 4140, they display magnetic properties. It is a ferritic grade, i.e., it contains a sizable quantity of ferrites (iron compounds), which makes its crystalline structure respond to a magnet.

The minimum carbon content in a B7M steel heavy hex bolt is 0.28%.
Buyers can demand demagnetisation procedures for these fasteners to match application-specific needs.

A193 B7M studs generally use UNC (Unified National Coarse) or 8 TP for components over 1 inch in diameter. The latter represents 8-UN or eight threads per inch if measured along the length of the bolt.

The threading specification is an essential factor to guarantee compliance with your application. We request customers to specify the thread pitch they desire with the size and processing needed for the fastener.

Only the best and tested quality ASME SA 193 gr B7M socket head cap screws and eye bolt offered by us with high power ultrasonic inspection reports

Extensive testing of B7M material guarantees its performance for various applications, like power plants and oil refineries. We use ultrasonic testing or UT (longitudinal beam) to detect defects, flaws, and discontinuities in the components.

Our quality control system gets handled by an expert team and contemporary testing mechanisms at each stage. The standard types of UT include pulse-echo and through-transmission.
Another crucial aspect of this specification is mandatory hardness testing for all the components (100%).

The recommended hardness value is 99 HRB.
We share all the test results and offer heat traceability in the Mill Test Certificates for an SA 193 Gr B7M eye bolt and other fasteners.

We are always ready to assist you with all SA193 B7M heavy hex bolt and square bolts supply requirement with short lead times

An ASTM A193 B7M threaded rod shows excellent corrosion resistance to chlorides and sulfides. It also resists hydrogen corrosion cracking. Its performance can be enhanced by one of these methods, depending on your requirements and budget:

• Coating with zinc, cadmium or Teflon
• Plating with nickel-phosphor or electroplating
• Cathodic protection using sacrificial anodes like magnesium or the “Impressed Currentâ€� technique with inert anodes like graphite

SA193 B7M square bolts and rods are perfect for challenging environments involving high temperatures and pressures. For example, they frequently work in chemical processing, petroleum, construction, and sewage/wastewater treatment.
