Normalizing
This is a process that’s usually used on forged or cast steel. It gives the metal a uniform grain structure, improving its toughness and making the metal more stable.
Annealing
This process is used to soften metals, making them more ductile and easier to work with. It also removes stress from the shaping or cutting processes. It is commonly used for making sheet metal and tools.
Does Stainless Steel Rust?
The short answer is: Yes, stainless steel can rust under specific conditions, but it is highly resistant to it compared to ordinary carbon steel. The term “stainless” is not absolute. Think of it as “stain-less” or “highly stain-resistant,” not “stain-proof.” Its renowned resistance to corrosion is due to its specific chemical composition. The Science Behind the […]
How Heat Treatment Works: The Basic Process
This process follows three main steps, and each must be followed correctly for the best outcome: Heating: Here, the metal you’re working with is heated to a certain temperature. The temperature used depends on the metal. Holding: This is when the workpiece is kept at the set temperature for a while, allowing it to […]
Essential Vernier Caliper Maintenance
Here’s a comprehensive guide to maintaining your vernier caliper for optimal accuracy and longevity: Essential Vernier Caliper Maintenance Daily Cleaning: Wipe Down After Every Use: Use a clean, soft, lint-free cloth (microfiber is ideal) to remove dust, coolant, metal chips, oil, fingerprints, and moisture. Pay special attention to the jaws, depth rod, and rack. Gentle Debris […]
What Is Heat Treatment?
Heat treatment is a method of changing a metal’s internal structure through precise heating and cooling cycles. This either makes the metal stronger or softer and easier to shape. The main aim of heat treatment is to improve the metal’s hardness and strength. Not only that, but it also improves its ductility and resistance […]
How to Choose the Right Forging Method
Choosing the best forging method depends on different factors: Part Size & Shape Use open-die forging for large or long parts like beams or shafts. The open tools let the metal spread freely. Closed-die forging for small or medium parts that need exact shapes or precise detail. Tolerances & Surface Finish Cold forging […]
Press Forging
Press forging uses steady, slow pressure to shape metal instead of quick hammer hits. It can be done hot, warm, or cold. The slow motion pushes metal deep into the die, giving a more complete fill and smoother outer surface. Because it presses rather than strikes, press forging imposes lower impact loads on the […]
Major Welding Methods
Here’s a comprehensive overview of major welding methods, presented entirely: Fusion Welding (Melts Base Metals & Filler) Arc Welding (Uses Electric Arc): Shielded Metal Arc Welding (SMAW) / “Stick Welding”: Process: An electric arc forms between a consumable electrode (stick) coated in flux and the workpiece. The heat melts the electrode tip and base metal, […]
Major Electroplating Methods
Here’s an overview of major electroplating methods, explained fully: Rack Plating (Still Tank Plating): Process: Parts are individually mounted onto custom metal fixtures (racks) which hold them securely and provide electrical contact. The entire rack is submerged into the plating bath. Applications: Complex, delicate, or large parts requiring precise control and uniform coating (e.g., automotive trim, aerospace […]
