Alloy steel bolts are high-performance fasteners designed to work in high-performance scenarios where other carbon steel bolts fail. These bolts are made much stronger and tougher by the addition of such elements as chromium, molybdenum, nickel, and manganese. The industry standard of the production of fasteners that may withstand heavy loads and extreme pressures is grades 4130, 4140, 4340 and 8620 (20MnCr5).
These bolts are normally provided in the quenched and tempered state. The heat treatment process makes the metal hard enough to resist wear yet tough enough to absorb the impact without breaking even when used in the process of low-temperature bolting. When it comes to structural steel creation or high pressure pipes, alloy steel bolts are a low-cost, high-strength answer that is not affected by dynamic stress.
Although alloy steel is mostly selected based on the strength-to-weight ratio, it is quite simple to exterior-treat it with such protective layers as PTFE, Zinc, or Hot Dip Galvanizing to prevent environmental corrosion. Heavy engineering gear to petrochemical refineries are the workhorse of essential industry infrastructure.

Types of Alloy Steel Bolts
Different industrial setups require specific bolt heads and threading. As a premier Alloy Steel Bolts Manufacturer in India, we supply:
Alloy Steel Bolts Grades
We manufacture and stock High Tensile Alloy Steel Bolts in specific ASTM grades designed for different temperature and pressure ratings:
Each grade is selected based on operating temperature, pressure, and load-bearing requirements.
Alloy Steel Bolts Specification
| Feature | Range / Detail |
|---|---|
| Size Range | M6 to M100 |
| Threads | UNC, UNF, BSW, Metric |
| Heat Treatment | Quenched & Tempered |
| Surface Finish | Black, Zinc Plated, Hot Dip Galvanized, PTFE Coated |
| Testing | Tensile, Hardness, Impact, PMI |
Manufacturing Process of Alloy Steel Bolts
The strength of an Alloy Steel Bolt comes from our controlled manufacturing process:
- Forging: Bolts are hot or cold-forged to ensure a continuous grain flow, maximizing strength.
- Heat Treatment: Controlled quenching and tempering are applied to achieve specific hardness levels.
- Machining: Precision threading (cut or rolled) is performed to meet ASTM/ASME tolerances.
- Coating: Application of protective layers like PTFE or Zinc to enhance durability.
Applications of Alloy Steel Bolts
- Energy: Power plants, boilers, and oil & gas pipelines.
- Infrastructure: Bridge building and structural steel fabrication.
- Heavy Machinery: Automotive, railways, and earth-moving equipment.
- Refineries: Petrochemical units and refinery pressure vessels.

Frequently Asked Questions About Alloy Steel Bolts
What is the difference between carbon steel and alloy steel bolts?
Carbon steel bolts rely primarily on carbon for strength, whereas alloy steel bolts contain extra elements like chromium and molybdenum. This makes alloy steel significantly stronger and better suited for extreme temperatures.
Why is heat treatment necessary for alloy steel bolts?
Without quenching and tempering, alloy steel would either be too brittle or too soft. The treatment ensures the bolt can handle high-torque tension without breaking.
Do alloy steel bolts rust?
Yes, alloy steel is more prone to rust than stainless steel. However, we provide various coatings (Zinc, Galvanized, or PTFE) to ensure they last in harsh outdoor or chemical environments.
