Adequate Supply Astm 4130 Steel S Outstanding Performance In Shipbuilding - China

ASTM 4130 steel excels in shipbuilding, mainly due to its high strength, good weldability and excellent corrosion resistance.

Here are a few key advantages of 4130 steel in shipbuilding: ### 1 - **High strength and fatigue resistance**

- ASTM 4130 steel is a low-alloy steel that contains chromium and molybdenum, which gives it extremely high strength and hardness after quenching and tempering.

This makes it particularly advantageous in parts that are subjected to high-intensity stresses, such as masts, hull frames and lifting gear of ships, which can effectively cope with the impact of waves and mechanical vibrations at sea.

### 2 - **Excellent corrosion resistance**

- Although ASTM 4130 steel is not a stainless steel, its chromium content makes it have certain corrosion resistance in marine environments, especially after appropriate surface treatment or coating protection.

This makes it suitable for critical structures of ships, especially in offshore and deep-sea applications, where it can maintain long-term stability and durability.

### Typical Applications

In shipbuilding, ASTM 4130 steel is commonly used in the following structural components:

- **Hull frame**: Provides support for the ship's load-bearing capacity.

- **Propulsion system parts**: Such as shaft and propeller components, which are subject to high-intensity rotational stress.

- **Lifting and hoisting equipment**: Such as the crane boom on the ship, which relies on the high strength and toughness of ASTM 4130 steel.

- **Critical connectors**: Joints and connecting parts used for welding, which remain strong in high-stress environments.
