8620 Steel Machining: Carburized Gears and Drivetrain Components

8620 Steel Machining: Carburized Gears and Drivetrain Components - Huaxiao precision manufacturing

8620 is a nickel-chromium-molybdenum carburizing steel chosen when a part needs a hard, wear-resistant surface over a tough, shock-resistant core. That profile makes 8620 steel machining the natural choice for gears, sprockets, drive shafts, and bearing races that see both load and impact. This guide explains how to machine 8620 and how to plan the […]

Nitrocarburizing Services: Low-Temperature Case Hardening for Wear & Corrosion Resistance

Nitrocarburizing Services: Low-Temperature Case Hardening for Wear & Corrosion Resistance - Huaxiao precision manufacturing

When a steel part needs a hard, low-friction, corrosion-resistant case but cannot tolerate the distortion of high-temperature hardening, nitrocarburizing is often the answer. This low-temperature thermochemical treatment builds a tough compound layer with minimal size change. Here is what nitrocarburizing services offer, how the variants differ, and how they compare to similar processes so you […]

Case Hardening Services: Build a Wear-Resistant Surface on a Tough Core

Case Hardening Services: Build a Wear-Resistant Surface on a Tough Core - Huaxiao precision manufacturing

Case hardening is the fastest way to make a steel part survive abrasion, fatigue, and impact without turning the whole component brittle. By enriching and hardening only the outer layer while keeping a tough, ductile core, you get components that shrug off surface wear yet still absorb shock underneath. Our case hardening services cover carburizing, […]

Carbonitriding Services: A Practical Guide to Low-Temperature Case Hardening

Carbonitriding Services: A Practical Guide to Low-Temperature Case Hardening - Huaxiao precision manufacturing

Carbonitriding services add a thin, hard, wear-resistant case to steel parts by diffusing both carbon and nitrogen into the surface at a relatively low temperature, then quenching to lock in the hardness. It is one of the most dependable ways to make small, high-volume components, gears, pins, and fasteners survive abrasive and fatigue-loaded service without […]

Carburizing Services: Case-Hardened Steel for Wear-Resistant Parts

carburizing-services - Huaxiao precision manufacturing

When a part must resist wear at the surface yet stay tough at its core, case hardening wins—and carburizing services are the most common way to get there. Carburizing diffuses carbon into a low-carbon steel surface, then quenches it into a hard martensitic case over a ductile interior. The result: gears, pins, camshafts, and bearing […]
