How do you write superscript in JavaScript?

JavaScript String sup() Method The sup() method is used to display a string as superscript text.

How a subscript character looks like?

A subscript or superscript is a character (such as a number or letter) that is set slightly below or above the normal line of type, respectively. It is usually smaller than the rest of the text. Subscripts appear at or below the baseline, while superscripts are above.

What does subzero mean in math?

Sub-zero literally means "beneath zero". As such, it is usually used for negative numbers; the most common usage refers to negative temperature.

What is the temperature of Sub-Zero?

Sub-zero temperatures are temperatures below zero degrees.

What is subzero treatment?

Sub-zero treatments are treatments in which components are cooled below room temperature. There can be many reasons to do this, but the main ones are to remove retained austenite from quenched components or tools, to increase the wear resistance of tools or to stabilise the component.

Why Austempering is done?

It is primarily used to improve mechanical properties or reduce / eliminate distortion. Austempering is defined by both the process and the resultant microstructure.

What is Hardenability of material?

The hardenability of a metal alloy is the depth to which a material is hardened after putting it through a heat treatment process. It should not be confused with hardness, which is a measure of a sample's resistance to indentation or scratching.

What is flame hardening?

Flame hardening is a heat treatment process where oxyfuel gas flames are directly impinged onto the gear-tooth surface area to be hardened which is then subjected to quenching. It results in a hard surface layer of martensite over a softer interior core.

How do you harden a flame?

Flame hardening is a common surface hardening method. Metal surfaces, such as steel, are heated with a high-temperature flame and then quenched. The result of flame hardening is a hard surface that is more resistant against wear and corrosion.

What is the case hardening process?

Case-hardening or surface hardening is the process of hardening the surface of a metal object while allowing the metal deeper underneath to remain soft, thus forming a thin layer of harder metal (called the "case") at the surface.

How do you flame harden 1045 steel?

Flame and induction hardening may be carried out by heating quickly to the desired case depth and quenching in water or oil. This should be followed by a tempering treatment at 300-400ºF (150-200ºC) to reduce stresses in the case without affecting its hardness.

Is 1045 a mild steel?

AISI 1045 steel is a medium tensile steel supplied in a black hot-rolled or normalized condition. It has a tensile strength of 570 - 700 MPa and Brinell hardness ranging between 170 and 210. ... AISI 1045 steel lacks suitable alloying elements and hence does not respond to the nitriding process.

What grade is 1045 steel?

Hot rolled 1045 steel bar is a medium carbon common steel grade with moderate weldability, higher strength, and impact properties for a variety of applications. 1045 steel is a common grade because of its cost and excellent properties.

What is the difference between 1018 and 1045 steel?

Medium-carbon steels are stronger than low-carbon steels, but not as easy to weld, and can be tempered by quenching. Yield strength for 1045 steel is much higher than that of 1018, at 76,900 psi, so if the steel needs to flex and return to its original shape, 1045 steel would be preferred to 1018.

CAN 1045 steel be heat treated?

HEAT TREATING 1045 can be flame or induction hardened, but not recommended for carburizing or cyaniding treatments.

What is the difference between 1040 and 1045 steel?

Real Life Applications 1045 has slightly increased tensile strength and yield strength numbers than 1040 as a result of a slightly higher carbon content. Also, as a result of higher carbon content, 1045 is not as easy to weld as 1040.
