What does the T in T10A 250V mean?

Material Name: Carbon Tool Steel Grade: T10A Standard:

GB T 1298-1986 Characteristics and scope of application: The strength and wear resistance of this steel are higher than those of T8 and T9, but the hot hardness is low, the hardenability is not high, and the quenching deformation is large. It is suitable for manufacturing various tools with poor cutting conditions, high wear resistance requirements, and is not subject to sudden and violent vibration, and requires a certain toughness and sharp knife edge, such as turning tools, planer knives, drills, paper cutters, low-precision and simple shape measuring tools (such as pallets, etc.), which can be used as wear-resistant zero chemical components that are not subject to large impact

The steel is delivered in annealed condition. By agreement between the two parties, it can also be delivered without annealing.

T--- indicates that it is a special fuse. Satisfied.

This is Lu is made in Shandong Province, B2 is seamless steel pipe, T10A is industrial seamless steel pipe.

The districts **, for example, the first district in the city is A, A runs out and then uses another letter, I bought a car at the end of 04 when it was already Lu, T and X start with a taxi.

Since each company's policy is different, it is recommended to call the insurance company** directly for consultation.

The difference between T10A and T10 is that one is a high-grade carbon tool steel and the other is a carbon tool steel. The content of sulfur, phosphorus and non-metallic inclusions of high-grade carbon tool steel is lower than that of carbon tool steel, and the mechanical properties are better.

The sulfur content in T10A is <=, the phosphorus content is <=, (the sulfur content during open-hearth smelting is <=

The sulfur content in T10 is <=, the phosphorus content is <=, (the sulfur content in open-hearth smelting is <=

The ingredients are not the same.

T10A has less control of harmful elements and is less prone to cracking when handled.

The strength and wear resistance of this steel are higher than those of T8 and T9, but the hot hardness is low, the hardenability is not high and the quenching deformation is large. It is suitable for manufacturing various tools with poor cutting conditions, high wear resistance requirements, and is not subject to sudden and severe vibration, and requires a certain toughness and sharp knife edge, such as turning tools, planer cutters, drills, paper cutters, and low-precision and simple shape measuring tools (such as pallets, etc.), which can be used as wear-resistant parts that are not subject to large impact.

General low hardenability cold work die steel, high-grade high-carbon tool steel, the advantage is that the machinability is good, cheap, easy, but the hardenability is poor, the quenching deformation is large, because the steel contains less alloying elements, low tempering resistance, and therefore low bearing capacity. Although it has high hardness and wear resistance, the toughness of the workpiece with small section is insufficient, and the blank with large section has a tendency to residual reticulated carbide.

The minimum heating temperature of the world is 740, the optimal isothermal temperature is 690-720, the heating temperature of flake carbide is 780, the heating softening temperature is 250, and the hardening depth is 15-18mm for water quenching and 5-7mm for oil quenching.

The steel is roughed in an annealed state, then quenched at low temperatures, tempered to high hardness, and then finished. Achieve high abrasion resistance and mirror finishing. Low-carbon martensitic low-temperature quenching is carried out to make it have high wear resistance and toughness, and prevent and reduce deformation and cracking.

T10A is one of the grades of premium carbon tool steel.

t10a

Main characteristics: good toughness, high strength, higher wear resistance than T8, T8A, T9, T9A, but low hot hardness, low hardenability, quenching deformation is large.

Application examples: used to manufacture tools with poor cutting conditions, high wear resistance, and not subject to strong vibration, requiring toughness and sharp edges, such as drills, taps, turning tools, planer cutters, reaming tools, wire drawing dies, cold cutting edge dies and punching dies with a diameter or thickness of 6 8mm and uniform cross-section, and wear resistant parts with little impact, such as small shafts, low-speed transmission bearings, lubricating shafts, pins, etc.

I strongly asked for additional points, and it took me 30 minutes to find it!

Used to make general dies, when the batch is 100,000 pieces, the punched material is a soft low-carbon steel plate, and the material thickness is less than 1mmT10A, which is a high-quality carbon tool steel, and the hardness is very high after quenching, reaching more than HRC55. Used as a cushion block in a fixture

10 steel is a high-quality carbon bucket husu structural steel, and its carbon content is.

T10 steel is a carbon tool steel with a carbon content of 1%.

The tail mark A indicates that the brittle impurities such as phosphorus and sulfur contained in it are very low, and the performance is the best among the same steels.

T is slow melting, 10A is 10 A, H is not clear, you don't know to go to Lanheng Electronics official ** to see, they **have.

HT200 is a grade of gray cast iron, HT stands for gray cast iron, and gray cast iron HT200 table.

Q235 is divided into four levels: A, B, C, D (GB700-88), and Q235A is included.

Q235B grade includes.

Q235C grade contains C

Q235D grade with C

Q stands for yield, which means that the yield strength is 235MPa, which is a very commonly used material.
