This should be a special-purpose steel, I guess: CL is a pinyin abbreviation for wheels, and 60 is the carbon content.

CL is the pinyin abbreviation of the vehicle, I only have the component of 50, and I did not find the 60.

CL is the pinyin abbreviation of the vehicle, and the chemical composition is similar to 60 steel.

GB T 699-1999 CL60 is an old grade, which is no longer used in the industry, and the corresponding new grade is 60 steel in carbon structural steel.

45 steel is the name in GB, also called"Oil steel"。The market is mostly spot hot-rolled; Between cold-rolled specifications.

No. 45 steel is a high-quality carbon structure steel, the hardness is not high and easy to cut, and it is commonly used in the mold to make templates, pins, guide pillars, etc., but it must be heat treated.

No. 45 steel is quenched and before tempering, and the hardness is greater than HRC55 (up to HRC62) is qualified. The highest hardness for practical application is HRC55 (high-frequency quenched HRC58).

Do not use the heat treatment process of carburizing and quenching for steel number.

Quenched and tempered parts have good comprehensive mechanical properties, widely used in motorcycles, automobiles, especially those connecting rods, bolts, gears and shafts working under alternating loads, etc., to bear huge friction in the work, usually using quenching methods to improve their own hardness, wear resistance and service life.

Main uses: 1. Shaft parts.

2. Blanks and materials of shaft parts.

3. In the field of mold repair.

American Standard Stainless Steel (S41500) - ASTM A182, equivalent to 0Cr13Ni4MO

Its chemical composition is as follows:

The mechanical properties after heat treatment are as follows:

Tensile strength: 655 ; yield: 517; Elongation: 18 ; Shrinkage: 35 ; Hardness: 207-243 Brinell hardness.

Because of its good mechanical properties and corrosion resistance, this material is widely used in nuclear power, petroleum machinery, valves and other fields.

A code name can represent many kinds of substances, and the chemical composition and content of them can be analyzed by femtosecond detection, and even trace components can be judged more accurately.

Indoor chemical pollution index in the range of 0-100 is normal.

The pollution index refers to an index that comprehensively represents the concentration and filtration characteristics of suspended solids and colloidal substances in the feed, and characterizes the degree of blockage of the microporous filter membrane by the feed.

There are many kinds of pollutants in the environment, even within the scope of local pollution, there is often more than one type of contaminant.

Air Pollution Index:

The pollution index items are tentatively defined as sulphur dioxide, nitrogen oxides and total suspended particulate matter.

Empty means: level I, index 0 50, air quality is excellent.

Level II, with an index of 51 100, the air quality is good.

At this time, air quality is considered acceptable and generally poses no danger to public health.

Level III(1) with an index of 101 150 indicates that the air quality is slightly polluted.

At this time, the health of people who are more sensitive to pollutants, such as children and the elderly, people with respiratory or heart diseases, and those who enjoy outdoor activities, are affected.

Level III (2) with an index of 151 200 and the air quality is lightly polluted.

At this time, almost everyone's health is affected, and the adverse effects are especially pronounced for sensitive groups.

The indices were 201 250 and 250 300, which were level IV (1) and IV (2), respectively, and the air quality status was classified as moderate and moderate heavy pollution, respectively. Spending a long time in such air may have a serious impact on everyone's health.

If the index is greater than 300, the air quality level is V, and the air quality status is heavily polluted. Being active in such air for a long time can seriously affect the health of all people.
