JADCO 400 & 450 STEEL

JADCO 400,450, 500

Impact and Abrasion Resistant Plate 


JADCO 400 & 450

A superior steel designed for moderate to high abrasion and impact applications.

Due to the heat-treating processes and chemistry JADCO 400 and JADCO 450 yields a lengthier service to the end user than a mild steel. With a low carbon and alloy content its properties allow for great capabilities weldability and forming. This product is popular because it does lend to being a more cost-effective material option.

JADCO 400

JADCO: 400 is a superior carbon-based impact and abrasion resistant wear plate.
JADCO: 400 provides a longer life than mild steel due to the heat-treating process and chemistry. The low carbon and alloy content allow for ease of weldability and forming.
JADCO: 400 is an excellent choice for a low-cost impact and abrasion resistant plate.

Fabrication Information

Cutting: JADCO: 400 is easily flame cut with oxyacetylene or plasma. Hardening will occur at the edge of the cut, therefore it’s beneficial to pre-heat before flame cutting (250°F) or allow enough stock to get below the hardened edge. Note: At JADCO, high-definition plasma is used to burn, and the material is under water to decrease distortion of the heat-affected area. When preheating the plate, do not heat directly with a torch, use indirect heat to heat evenly over the entire plate.

Machining: JADCO: 400 is accepting to conventional equipment for universal machining, which includes, and is not limited to countersinking, counterboring, drilling and milling.

Forming: Plate 3/4" and thinner can be cold bent to a minimum inside bend radius of 6T, with bend axis transverse to the rolling direction. Greater than 3/4", a radius of 8T should be used. Hot forming or stress relief operations are not recommended for 1” and thinner plates. Maximum heat of 480°F for plate over 3/4" thick. Higher temperatures may change mechanical properties. Bending should follow good practices, including, but not limited to: grinding of plate edges, die lubrication, conditioning and uniform load application.

Welding: JADCO: 450 may be welded using simple procedures and readily available consumables due to its superb weldability. JADCO does not recommend high heat input welding due to the possible reduction of the mechanical properties and hardness. Pre-heating is recommended for plates over 1-1/2” thick.
