What Is the Difference Between 1Cr14mn10ni1 and 304 Stainless Steel?
Different Performance
1Cr14Mn10Ni1 is austenitic stainless steel.
Austenitic stainless steel in addition to oxidizing acid medium corrosion, if it contains Mo, Cu, and other elements can also be resistant to sulfuric acid, phosphoric acid, as well as formic acid, acetic acid, urea, and other corrosion.
If the carbon content of such steel is less than 0.03% or Ti, Ni can significantly improve its resistance to intergranular corrosion. High silicon austenitic stainless steel has good corrosion resistance to concentrated nitric acid.
304 stainless steel is a common material in stainless steel, density 7.93g/cm3, also called 18/8 stainless steel in the industry. High-temperature resistance of 800 ℃, with good processing performance, and high toughness, widely used in industry and furniture decoration industry and the food and medical industry.
Different Applications
Austenitic 304 stainless steel plate, is claimed that this material can bring extremely strong rust and corrosion resistance, but also has excellent plasticity and toughness, which is convenient for stamping and molding.
With a density of 7.93g/cubic centimeter, 304 stainless steel is a very common stainless steel, also called 18/8 stainless steel in the industry. Its metal products are resistant to high temperatures and have good processing performance, so it is widely used in the industrial and furniture decoration industry and food and medical industry.
304 stainless steel is the most widely used kind of chromium-nickel stainless steel, as a kind of widely used steel, has good corrosion resistance, heat resistance, low-temperature strength, and mechanical properties; stamping, bending, and other hot workability are good, no heat treatment hardening phenomena.
Resistant to corrosion in the atmosphere, in case of industrial atmospheres or heavily polluted areas, it needs to be cleaned promptly to avoid corrosion. Suitable for food processing, storage, and transportation. Has good processing performance and weldability.
Different Production Processes
Chromium-nickel austenitic stainless steel has excellent thermoplasticity so that it is easy to apply forging, rolling, hot perforation extrusion, and other thermal processing, with ingot heating temperature of 1150 ~ 1260 ° C, and the deformation temperature range is generally 900 ~ 1150 ° C, copper-containing, nitrogen, and titanium, niobium-stabilized steel leaning towards low-temperature, and high-chromium, molybdenum steel leaning towards high-temperature.
Due to poor thermal conductivity, the holding time should be longer. After hot working, the workpiece can be air-cooled. Chromium-manganese austenitic stainless steel thermal Cracking sensitivity is stronger, the ingot opening billet should be small deformation, multi-channel, and forgings should be stacked cold.
304 stainless steel products color spray art processing method of the process is stainless steel products → silksCreen → etching → alkali treatment → silksCreen → oxidation coloring → alkali treatment → finished products.
The process of etching art processing method of stainless steel products is stainless steel products → silksCreen → etching → alkali treatment → oxidative coloring → finished products.
The chemical coloring method of stainless steel does not use pigments and dyes but immerses the stainless steel in a heated concentrated chromium sulfate solution for chemical coloring, which is characterized by good food resistance. The ink used in this processing method should have very strong acid resistance and generally use UV vulcanized ink with special properties compatible with the treatment process.
What Should the Metallographic Organization of 3Cr13 Round Steel in Annealed Condition Look Like? Is It Normal for the Carbides to Be Distributed in An Interrupted Network?
Process: Raw material in annealed condition
Etching method: Chlorinated high iron hydrochloric acid aqueous solution etching
Description of organization: Punctate and spherical pearlite and the intermittent distribution of secondary carbides along grain boundaries. Hardness is 207 HRB.
3Cr13 type stainless steel, steel contains 13% chromium, because chromium has the isothermal transformation curve to the right, and improves the hardenability of steel, so that the steel has air-quenching ability. If air cooling after forging, due to the production of martensitic transformation, and produces a large volume effect and organizational stress. Easy to produce after forging Cracks, so 3Cr13 steel forging must be annealed immediately after processing, on the one hand, to eliminate stress, on the other hand, conducive to the future cutting and quenching for the future organization.
The annealed state of 3Cr13 steel mechanical properties are poor, and corrosion resistance is not good, this is due to a large number of chromium and carbon formation (Cr, Pe) 23C6, so the matrix is poor chromium. So 3Cr13 steel is generally not used in the annealed condition but in quenched and tempered condition.
Which Is Harder, Sharp Steel or 3Cr13 Steel?
Frontier steel, also known as high-speed steel, is an alloy tool steel;
3Cr13 steel is a medium carbon stainless steel, that belongs to the alloy structural steel.
On the hardness alone is of course high-speed steel hardness, it can be 3Cr13 steel cutting, but more brittle.
If used to make daggers, or 3Cr13 steel is more appropriate, well after carburizing or boronizing, surface cyanide treatment is better. The surface hardness goes up, while the internal material is still very tough, which can ensure sharpness and strength.
Corrosion resistance is not too much different, 3Cr13 steel is slightly better.
