VR 16 is a versatile medium-carbon alloy steel commonly used for machine parts, industrial components, shafts, bolts, gears, and engineering applications requiring a balance of toughness, strength, and machinability. It belongs to the category of general-purpose engineering steels and is formulated to deliver good performance under moderate mechanical loads.

VR 16 is known for its consistent machinability, uniform mechanical properties, and ease of fabrication, making it suitable for industries such as automotive, fabrication, machinery manufacturing, steel structures, and general engineering.

Key Properties of VR 16

1. Good Machinability

VR 16 is easy to turn, drill, mill, and thread. It does not cause excessive tool wear and allows fast machining cycles, saving time in production.

2. Moderate Strength & Toughness

Because of its medium carbon content, VR 16 provides good strength and impact resistance. It can handle dynamic loads and is commonly used in rotating parts like shafts and pins.

3. Excellent Weldability

With controlled carbon levels, it can be welded without major risks of cracking. Standard welding processes (MIG, TIG, Arc) work reliably.

4. Suitable for Surface Hardening

VR 16 can be carburized or induction hardened to achieve a hard outer layer while keeping a tough, shock-resistant core. This is ideal for parts that require wear resistance on the surface.

5. Good Dimensional Stability

It maintains shape during machining and heat treatment, making it reliable for precision engineering components.

Common Applications

1. Machine shafts

2. Nuts, bolts, studs

3. Automotive components

4. Bushes and pins

5. Agricultural machinery parts

6. Flanges and brackets

7. Forged components

8. Structural steel parts

9. General-purpose industrial hardware

Summary

VR 16 is a dependable, medium-carbon engineering steel known for its excellent machinability, good strength, toughness, and weldability. It performs well in a wide range of industrial applications and is suitable for components that must withstand moderate loads or require surface hardening. Its versatility and cost-effectiveness make it one of the commonly used grades in general engineering and fabrication sectors.
