What kind of metal is HW and what steel does HW stand for

It is not a metal, just a unit of hardness.

Summary. Hello dear! The meaning of HWS alloy is that HWS is an alloy special steel used in hot water supply systems.

Hello dear! The meaning of HWS alloy is that HWS is an alloy special steel used in hot water supply systems.

Alloy steel is to add other alloying elements to the steel in addition to iron and carbon, which is called alloy steel. Alloying elements have a great influence on the microstructure and properties of steel, and its main role is to strengthen the ferrite, form alloy carbides, refine the grains, and improve the hardenability and tempering stability of the steel.

Alloy steel can be divided into alloy structural steel according to different uses, which is used to manufacture mechanical parts and engineering structures; alloy tool steels, steels used to make various tools; Particularity: Steel, which has some special physical and chemical properties. According to the different classifications of the total content of alloying elements, it can be divided into:

Low-alloy steel, the total content of alloying elements is less than 5%; (medium) alloy steel, the total content of alloying elements is 5 10%; High-alloy steel, the total content of alloying elements is greater than 10%. Alloy steel is mainly used in the occasions where wear resistance, backear corrosion resistance, high temperature resistance, low temperature resistance, non-magnetic and other requirements are required.

<>HW usually refers to the wide flange of H-beam. H-beams are divided into hot-rolled H-beams and welded H-beams (H). There are three types of hot-rolled H-beams: wide flange H-beams (HW), mid-flange H-beams (HM) and narrow flange H-beams (HN).

HW is the height of H-shaped steel and the width of the flange are basically equal, mainly used for steel core columns that have not been dismantled in reinforced concrete frame structure columns, also known as rigid steel columns, mainly used for columns in steel structures. HM is the ratio of the height of the H-beam to the width of the flange is about It is mainly used as a steel frame column in a steel structure, and as a frame beam in a frame frame structure under dynamic load.

For example: device platform. Hn is the ratio of the height of the H-beam to the width of the flange greater than or equal to 2.

It is mainly used for beams. The use of I-beams is equivalent to the HN beam.

1. Usually defined as the wide flange of H-shaped steel, HW is the height of H-shaped steel and the width of the flange are basically equal, mainly used for the steel core column in the reinforced concrete frame structure column, also known as the stiff steel column, which is mainly used for the column in the steel structure.

2. Steel is a general term for iron-carbon alloys with a carbon content and mass percentage between to, and the chemical composition of steel can vary greatly, and the steel containing only carbon elements is called Youming carbon steel punching (carbon steel) or ordinary steel.
