Product Application

Due to its strong load-bearing capacity, 1045 Steel Plate is widely used in the following fields:

1. Mechanical manufacturing: used for manufacturing gears, bearings, connecting rods, and crankshafts.

2. Mold industry: suitable for low to medium precision mold bases, templates, and brackets.

3. Heavy equipment: excavator wear-resistant parts, agricultural machinery frames, and conveying systems.

4. Fasteners: Manufacturing high-strength bolts, washers, and locating pins。

Precautions for use

1. Welding preheating: Due to the high carbon content, direct welding is prone to cracking. It is recommended to preheat to 150-250 ° C before welding and slowly cool down after welding.

2. Quenching medium: When performing hardening treatment, it is recommended to use oil quenching to reduce the risk of deformation and cracking; If pursuing extremely high hardness, water quenching requires strict control of cooling time.

3. Storage rust prevention: This material does not contain rust prevention elements such as chromium. Long term storage requires applying rust prevention oil or maintaining a dry environment.

FAQ

Q: What is the surface hardness that 1045 Steel Plate can achieve?

A: By induction hardening or flame hardening, its surface hardness can usually reach around HRC 54-60. But please note that the heart will still maintain good resilience.

Q: Do you provide material certification for your steel plates?

A: Yes, all steel provided by Sanhe Steel comes with an original material list (MTC), which includes chemical composition analysis and physical and mechanical property testing data.

Q: Is 1045 Steel Plate suitable for laser cutting?

A: Very suitable. Our board has good flatness, low impurity content, small heat affected zone during laser cutting, and a smooth cut, which can effectively reduce the workload of secondary processing.
