Laser Cutting

Laser cutting represents the cutting-edge in thermal cutting technology, offering rapid cutting capabilities with minimal heat input. In this process, the steel is vaporized and removed from the cut edge by the intense heat of the laser. The precision of the laser beam ensures that only a very small area is affected by heat, resulting in a clean, flawless cut edge. Known for its exceptional accuracy, laser cutting is capable of handling wear plate thicknesses ranging from a mere 0.5 mm to a substantial 30 mm.

Thermal Cutting

Flame cutting is a prevalent method for thermally severing materials. In this technique, a gas burner is utilized to heat the steel to a high temperature. Once the steel reaches its ignition point, a jet of gas is directed at it, blowing away the molten metal and effectively dividing the material into two distinct parts. This process is renowned for its ability to produce high-quality, perpendicular cuts on thick steel plates. The thickness of wear plate that can be cut varies widely, from as little as 3 mm to as much as 300 mm, contingent upon the type of burner employed.

Wear-resistant plates, or abrasion-resistant plates, are crucial in industries where durability against wear and tear is paramount. These plates are valued for their high alloy content and hardness, but improper processing can lead to cracking. Here, we discuss common types of cracking and effective strategies to mitigate them.

Common Types of Cracking During Processing

Cut-Edge Cracking

Occurs with thermal cutting methods (flame, plasma, laser) and is visible from 48 hours up to several weeks post-cutting. Influenced by hydrogen content and residual stresses in the steel plate.Definition & Causes:

Prevention Tips:

Initiate cutting while the material is still warm to reduce the risk.Pre-Heat the Plate:
This reduces residual stress, though not as effectively as pre-heating.Slow Cutting Speed:
Apply heat immediately after cutting and allow slow cooling to minimize cracking risk.Post-Heat or Slow Cooling:

Weld Cracking

Challenging due to cracking in the weld metal or heat-affected zone, influenced by cooling speed, hydrogen content, and filler metal.Definition & Causes:

Prevention Tips:

Ensure joint cleanliness to prevent hydrogen cracking.Clean Welding Surface:
Similar to cutting, these methods reduce the heat-affected zone and prevent cracking.Pre-Heating & Slow Cooling:
Choose filler metal based on the base metal’s tensile strength to combat cracking.Appropriate Filler Metal:

Bend Cracking

Difficult due to the plate’s high strength and poor elasticity.Definition & Causes:

Prevention Tips:

Before bending, understand the allowable bending degree on the product quality certificateCheck Inspection Certificate:
Ensure precise bending to achieve flawless finished products.Account for Bend Allowance:
Guarantees a smooth, clean productUse a Press Brake:

Steel Plates Purchased Through Official Channels from Baohui Steel Limited Come with an Inspection Certificate as Shown Below

In the product quality certificate, you can find a section labeled "Bend Test," which specifies the safety margins to be observed during bending.

The "90°" represents the maximum bending angle.
"D" represents the minimum diameter of the bending center.
"A" represents the thickness of the steel plate.

For businesses utilizing wear-resistant steels, high-strength steels, or other thick steel materials, implementing proper measures to prevent cracking can significantly reduce costs. Always consult the processing guide specific to your plate brand, as each mill has its own standards for pre-heat temperature, cutting speed, and filler metal. Adhering to these guidelines can largely prevent cracking issues.Suggestion:
