Why is is high carbon steel is limited to cutting tools?
Higher contents of carbon make the steel harder but more brittle. The harder steel will cut better and hold an edge longer but has much less shear strength.
What is 440F stainless steel?
440A is a US standard of a martensitic stainless steel. It is known to keep a hard edge but not as tough as some of the other martensitic stainless steel.
What should you do if the lap for steel reinforcement is to short but is already in concerete?
Drill out the edge of the slab and add some dowels....or cut the slab back.
Is Laser cutting of steel a thermal cutting process?
CO2 laser cutting carbon steel with oxygen is an exothermic (thermal) process. The oxygen used with the laser cutting burns the steel, thus assisting the cutting process. This process causes striations, or lines, to form at the cutting edge and provides lower cut quality but faster cutting. In contrast, when cutting stainless steel with nitrogen, only the heat from a CO2 laser performs the melting (operating in the far infrared region at 10600 nanometers). The nitrogen assist gas pushes the melted material down and out of the way, leaving the cut that is typically a polished edge.
How many tons can a one meter square 20mm thick steel plate hold?
Firstly the question needs to be defined further: -How is the load applied, distributed or point loading? -How is the steel plate supported one edge, two edges , three edges or all four?
What are the three main types of steel and what are they used for?
Steel is an alloy of iron and carbon. Depending on the percentage carbon present , the types of steel are 'Forged Steel, Sheet steel, and Razor strip.. Forged steel for making tools, railway train wheels, girders etc.,s Sheet steel for making cars, cookers and refrigerators etc., Razor Strip for any steel the requires a sharp edge(knives). Stainless Steel is an alloy of steel , nickel, and chromium. It is a steel that will neither discolour, nor rust. However, a razor sharp edge cannot be honed onto it. There are also various hardened steels, using tungsten, molybdenum etc., for railway line switches/points.
What is the geometric figure of edge of a sheet of paper?
nonagon
What does a Chamfer do?
A chamfer 'breaks' a sharp edge. eg. after drilling a hole, it is normal practice, especially after drilling in metal to chamfer the edge. eg. chamfers can be made to the edges of prepared wood to prevent the edge breaking away, or causing splinters. Generally the most common form of chamfer is one of 45º
A sword-shaped tool used to true the edge of knives?
Steel
How do you figure out the square root of 2?
You divide the long edge of a sheet of A4 paper by the shorter edge of the paper.
What are the other materials in steel?
Steel is an alloy of iron and Carbon. The carbon content ranges from 0.1% to 2% . Depending on the carbon content , different types of steel are made. e.g. Forged Steel Railway lines Railway rolling stock wheels and axles. Steel tools (Spanners/ hammers etc.,) Sheet Steel for building ships, cars and white goods. Razor strip, for honing to a sharp edge. Steel can also have a percentage of other metals present, notably. chromiun, nickel, and tungstem. Alloyed with chromiun and nickel forms 'stainless steel' to prevent rusting (cutlery) Alloyed with tungstem, produces hard wearing steel; railway lines points/crossovers. Phosphorus and sulphur can also be present to produce a steel with certain other characteristics.
What advantage does stainless steel have over cast iron?
Steel is stronger, more flexible and can hold an edge better.
What is a selvedge used for?
To prevent the edge of a woven fabric from fraying.
What are the sheets of ice that break off the edge of Antarctica?
Glacier tongues that break off the Antarctic ice sheet are called icebergs once they disconnect from the sheet.
How do you get edge dressing off of wood flooring?
Steel wool and paint thinner
Why is a knifemade of metal?
A steel bladed knife will hold a sharp cutting edge.
Can you sharpen a sword to an edge no thicker than a molecule?
You certainly can, although it either breaks or corrodes almost instantaneously. A stable edge can get very close, though.
