1. What is a stainless steel angle?

Stainless steel angle steel is a type of steel that has three sides, a bottom, and a right-angled shape. It is a steel object with two perpendicular sides that is right-angled. It possesses all of stainless steel's traits and qualities. It can be separated into equilateral and unequal sides depending on the shape. It can create various structures capable of withstanding stress or act as a linking structure. It is a crucial and frequently used material in the modern construction sector and is utilized in many different modern construction projects.

Classification of stainless steel corners:

1. According to the purpose, it can be divided into structural profiles for bridges, ships, offshore structural profiles, etc. 2. According to the cross-sectional shape, it is divided into simple cross-section profiles and complex cross-section profiles. 3. According to materials, they are divided into ordinary carbon structural profiles and alloy structural profiles. 4. According to the production method, it is divided into two categories: hot-rolled tube type and cold-drawn tube type. 5. According to wall thickness, it is divided into two types: thin-walled steel pipe and thick-walled steel pipe.

Common stainless steel angle steel characteristics:

1. 304 stainless steel angle steel: It has good weldability and corrosion resistance, good cold workability, low-temperature strength, and no heat treatment hardening phenomenon. 2. 316 stainless steel angle steel: corrosion resistance, strong atmospheric corrosion resistance, stable high-temperature strength. 3. 321 stainless steel angle steel: strong resistance to crystal corrosion. 4. 410 stainless steel angle steel: strong resistance to welding deformation and high-temperature resistance 5. 430 stainless steel angle steel: strong corrosion resistance, good formability, and excellent high-temperature oxidation resistance. 6. 420 stainless steel angle steel: High quenching hardness and magnetic.

Yield point (σs)

When the steel or sample is stretched, when the stress exceeds the elastic limit, even if the stress no longer increases, the steel or sample continues to undergo significant plastic deformation. This phenomenon is called yielding, and the minimum stress value when yielding occurs is for the yield point. Assume Ps is the external force at the yield point s, Fo is the cross-sectional area of the sample, and then the yield point σs = Ps/Fo (MPa).

Yield strength (σ0.2)

The yield point of some metal materials is extremely unclear and difficult to measure. Therefore, in order to measure the yield characteristics of the material, the stress when the permanent residual plastic deformation is equal to a certain value (usually 0.2% of the original length) is specified, which is called the condition. Yield strength or simply yield strength σ0.2.

Tensile strength (σb)

The maximum stress value reached by the material from the beginning to the time of fracture during the stretching process. It indicates the steel's ability to resist fracture. Corresponding to tensile strength are compressive strength, flexural strength, etc. Assuming that Pb is the maximum tensile force reached before the material is broken, Fo is the cross-sectional area of the sample, then the tensile strength σb = Pb/Fo (MPa).

Elongation (δs)

After the material is pulled apart, the percentage of its plastic elongation length to the original sample length is called elongation or elongation.

Yield-strength ratio (σs/σb)

The ratio of the yield point (yield strength) of a material to its tensile strength is called the yield ratio. The larger the yield-strength ratio, the higher the reliability of structural parts. Generally, the yield-strength ratio of carbon steel is 0.6-0.65, and that of low-alloy structural steel is 0.65-0.75. Alloy structural steel is 0.84-0.86.

Hardness

Hardness indicates a material's ability to resist hard objects pressing into its surface. It is one of the important performance indicators of metal materials. Generally, the higher the hardness, the better the wear resistance. Commonly used hardness indicators include Brinell hardness, Rockwell hardness, and Vickers hardness.

4. Physical properties of stainless steel angle

1. Thermal expansion coefficient: changes in material mass elements caused by temperature changes. The expansion coefficient is the slope of the expansion-temperature curve, the instantaneous expansion coefficient is the slope at a specific temperature, and the average slope between two specified temperatures is the average thermal expansion coefficient. The expansion coefficient can be expressed in terms of volume or length, usually in terms of length.

2. Density: The density of a substance is the mass per unit volume of the substance, and the unit is kg/m3 or 1b/in3.

3. Elastic modulus: When applying force to both ends of a unit length rib can cause a unit change in the length of the object, the force required per unit area is called the elastic modulus. The unit is 1b/in3 or N/m3.

4. Resistivity: The resistance measured between two opposite sides of a cube of unit length, expressed in units of Ω·m, μΩ·cm or Ω/(circular mil.ft).

5. Magnetic permeability: a dimensionless coefficient that indicates the degree to which a material is easily magnetized. It is the ratio of magnetic induction intensity to magnetic field intensity.

6. Melting temperature range: Determine the temperature at which the alloy begins to solidify and finishes solidifying.

7. Specific heat: The amount of heat required to change the temperature of a unit mass of a substance by 1 degree. The values of specific heat in the imperial and CGs systems are the same because the unit of heat (Biu or cal) depends on the amount of heat required to raise the unit mass of water by 1 degree. The numerical value of specific heat in the SI system of units is different from that in the Imperial or CGS system because the unit of energy (J) is defined differently. The units of specific heat are Btu (1b·0F) and J/(kg·k).

8. Thermal conductivity: a measure of the rate at which a substance conducts heat. When a temperature gradient of 1 degree per unit length is established on a material with a unit cross-sectional area, then the thermal conductivity is defined as the heat conducted per unit time. The unit of thermal conductivity is Btu/(h·ft·0F) or w/(m ·K).

9. Thermal diffusivity: It is a performance that determines the rate of temperature progression inside a substance. It is the ratio of thermal conductivity to the product of heat and density. The unit of thermal diffusivity is Btu.
