Laser Quenching of AISI 4130: +47% Wear Resistance at the Cost of Corrosion
Laser quenching of AISI 4130: a double-edged sword In oilfield service, surface wear is not a detail: it accounts for more than 90 % of component failures. That is why the industry is turning increasingly to laser
Simulation-First Laser Quenching: Using ANSYS Temperature Field to Find the 4145H Process Window
By Harris, Technical Staff, SHUNFU METAL There is one variable you can never measure directly on a laser-quench line: the surface temperature during the beam pass. It rises and collapses in fractions of a second, and
4145H Laser Quenching: The Golden Window Where Hardness Peaks and Wear Drops — 2 kW, 400 mm/min
By Harris, Technical Staff, SHUNFU METAL Laser quenching process sheets usually promise one number: a single hardness, a single speed, a single power. The 2021 study by Liang Chenfan et al. (Transactions of Materials and Heat
4145H Laser Quenching Parameters: How Power and Scan Speed Control Hardness and Wear Mode
By Harris, Technical Staff, SHUNFU METAL Laser quenching is a two-dial process: laser power and scanning speed. Spot size and track overlap are geometry; everything that matters for hardness and wear sits on those two dials.
Laser Quenching vs Induction Hardening for 4145H Drill Collar Steel: Why Precision Wins
By Harris, Technical Staff, SHUNFU METAL Laser quenching — laser transformation hardening — is the fastest-growing surface treatment in the drilling industry, yet most drill collar buyers still specify induction or whole-part hardening out of habit.
