General principles of machining stainless steels Introduction. The most common and hence most frequently machined stainless steels are the austenitic types, such as grades 304 (1.4301) and 316 (1.4401). These are characterised by their high work hardening rates and poor chip breaking properties during machining.

Precipitation Hardening Stainless Steel. Precipitation hardening (PH) stainless steels are also corrosion-resistant alloys, some of which can be heat treated to provide tensile strengths of 850MPa to 1700MPa and yield strengths of 520MPa to 1500MPa or more-its strength is approximately three to four times that of austenitic stainless steels.

Surface Hardening by Carburizing - Engineering Lab Reports

Surface hardening by carburizing can be classified into three kinds; solid carburizing, liquid carburizing and gas carburizing. In each of these three processes, certain chemicals and methods are used, for the solid carburizing we use charcoal, and in liquid carburizing we use Cyanide (CN) but in gas carburizing we use carbon monoxide gas (CO).

STAINLESS STEEL AND THEIR TYEPS - SlideShare

Jan 02, 2018· 7 Martensitic stainless steel Martensitic stainless steel contains chromium (12–14%), molybdenum (0.2–1%), nickel (less than 2%), and carbon (about 0.1–1%) (giving it more hardness but making the material a bit more brittle). Martensitic stainless steels are not as corrosion-resistant as the other two classes but are extremely strong and ...

Coatings for tribocorrosion protection - ScienceDirect

Jan 01, 2011· Unfortunately, conventional approaches for coating selection are reliant on hardness (H) alone but more recently selections use H/E ratios (which relate to the ability of the surface to store elastic energy, where E is the elastic modulus) or H 2 /E* 3 (the so-called plasticity index, E* = E/(1 − ν 2)), where ν is Poisson's ratio, both ...

Gear manufacturing process report

Gear manufacturing process report Gear manufacturing refers to the making of gears. Gears can be manufactured by a variety of processes, including casting, forging, extrusion, powder metallurgy, and blanking. As a general rule, however, machining is applied to achieve the final dimensions, shape and surface finish in the gear.
