Boiler pressure alloy steel pipe layout temperatures up to 580 ℃

Abstract: The boiler pressure alloy pipe layout is high-quality carbon steel, appropriate to participate in one or more alloying elements used to advance the permeability of the mechanical properties of steel , patience and quenching . Such steel production of goods , generally used in heat treatment ( normalizing or quenching and tempering ) ; zero , in the use of parts , the general demand for quenched and tempered or look through chemical disposal ( carburizing , nitriding , surface hardening ) or high frequency quenching disposal . Thus , according to the chemical composition ( carbon content first and foremost ) , heat treatment technology and the use of

Boiler pressure alloy pipe layout is based on high-quality carbon steel, appropriate to participate in one or more alloying elements used to advance the permeability of the mechanical properties of steel , patience and quenching . Such steel production of goods , generally used in heat treatment ( normalizing or quenching and tempering ) ; zero , in the use of parts , the general demand for quenched and tempered or look through chemical disposal ( carburizing , nitriding , surface hardening ) or high frequency quenching disposal . Thus , according to the chemical composition ( carbon content first and foremost ) , heat treatment technology and usefulness is not the same , these steels can be divided into carburizing , quenching and nitriding steel three .

A data boilers with high pressure alloy pipe . Primary layout for boiler steel production, the use of temperature up to 580 ℃ , high temperature requirements , high- strength steel, normalized and tempered steel to .

Test seamless metallic inclusions

1 . Range

This standard specifies the mapping assessed using standard compression ratio is greater than or equal to three rolling or forging of non-metallic inclusions in steel

Material microstructure evaluation method .

2 Sampling

Form of the inclusions in the steel depends largely on the degree of compression , so only after a degree of similarity becomes

Shaped cross section of the sample prepared in blank measurement is possible on a comparison of the results .

Inclusion content for measuring polished surface area of the sample should be approximately 200mm2 (20mm X10mm), and parallel to the steel

Vertical axis , the outer surface of the steel to the center in the middle .

If the product standard does not specify the sampling method is as follows :

- 40mm diameter or length was longer than the bars or billets : test surface is the outer surface of the steel to the center of the middle position

Radial cross-section portion

3 . Principle

The examination centers observed compared with the standard map , and were carried out for each type of inclusions rating.

These ratings picture is equivalent to 100 times lower longitudinal polished plane square area of 0.50mm2 field of view .

According to the morphology and distribution of inclusions , the standard rating chart is divided into A, B, C, D and DS five categories.

Inclusions in these five categories represent the most commonly observed type and shape of inclusions :

- A Class ( sulfide ) : a high ductility , has a wide range of aspect ratios ( length / width ) of a single gray

Colored inclusions, were generally rounded ends .

- B Class ( alumina-based ) : The majority is not deformed , with the angle , aspect ratio is small ( typically < 3 ) , with a black or blue

Colored particles are arranged in a row along the rolling direction ( at least 3 particles) .

- C Class ( silicate ) : a high ductility , has a wide range of aspect ratios ( usually ≥ 3) the individual was black

Dark gray color, or inclusions, generally an acute angle end .

- D Class ( globular oxides ) : no deformation, with an angular or circular , the aspect ratio is small ( typically < 3 ) , black, or

Bluish , irregular distribution of the particles .

- DS class ( single particle spherical category ) : round or nearly round, diameter ≥ 13μm single- particle inclusions .

Each type of inclusions and particles according to the width of the non-metallic inclusions were divided into two thin lines and thick lines series,
