How to harden & temper mild steel

Hardening steel is an essential part of any blade-making process. When exposed to heat, carbon molecules in steel realign themselves in a harder, stronger pattern, allowing a blade to hold an edge. Two processes are necessary to harden steel: the initial hardening, or heat treating, and tempering.

What is Annealing? Heat Treatment of Steels - Bright Hub

Annealing is a process by which the property of steel is enhanced to meet the machinability requirements. Annealing is a process of heating the steel slightly above the critical temperature of steel i.e. 723 Degree Centigrade and allowing it to cool down very slowly. There are various types of annealing. They are as follows: full annealing, process annealing, stress relief annealing

Steel Pipe and Manufacturing Processes Introduction The advent of rolling mill technology and its development during the first half of the nineteenth century also heralded in the industrial manufacture of tube and pipe. Initially, rolled strips of sheet were formed into a

Solid Waste Management in a Steel Plant – IspatGuru

Basic oxygen steel making The main waste materials in the BOF steel making are converter slag, scrap, waste refractories, converter muck, and gas cleaning plant (GCP) sludge. Except GCP sludge all other waste materials are usually generated in mixed condition which means that during generation one waste material gets contaminated with other waste material.

Non-Traditional Methods For Making Small Holes | …

However, the process is "blind" to considerations of material hardness, drilling with ease, stainless steel, carbide and other metals that are difficult to machine by conventional methods. Holes can be drilled at an angle to the surface, and there is no problem with "walking" when starting a hole on a curved surface.

Steel Production

Coal is a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the volatile matter such as oil, tar, hydrogen, nitrogen and sulfur are removed.

The Entire History of Steel - Popular Mechanics
