What are the characteristics of 1Cr18Ni9Ti stainless steel?

1Cr18Ni9Ti stainless steel is a stainless steel alloy widely used in various industries. It is often preferred due to its excellent corrosion resistance, strength and temperature resistance compared to other alloys.

1Cr18Ni9Ti stainless steel is a titanium-stabilized austenitic chromium-nickel stainless steel developed to provide an 18-8 type alloy with improved resistance to intergranular corrosion. The material is stabilized by the addition of titanium to prevent the formation of chromium carbides. Since titanium has a stronger affinity for carbon than chromium, titanium carbide precipitates within grains rather than forming at grain boundaries. Typical applications for 1Cr18Ni9Ti stainless steel include expansion joints, aircraft engine components, furnace components, heat exchangers, beneficiation screens, welding by all standard methods, with or without filler metal.

What is the heat treatment specification and metallographic structure of 1Cr18Ni9Ti?

Specifications for heat treatment: 1) Rapid cooling at 920-1150°C for solid solution; 2) Stabilization treatment can be carried out according to the requirements of the purchaser. The heat treatment temperature is 850-930°C, but it must be specified in the contract.

Metallographic structure: The structure is characterized by austenitic type.

Delivery status: Generally, it is delivered in a heat treatment state, and the type of heat treatment is specified in the contract; if it is not specified, it is delivered in a non-heat treatment state.

Is 1Cr18Ni9Ti stainless steel magnetic?

1Cr18Ni9Ti stainless steel is a titanium stabilized austenitic stainless steel with good general corrosion resistance. It has excellent resistance to intergranular corrosion after exposure to the chromium carbide precipitation temperature range of 800–1500°F (427–816°C). 1Cr18Ni9Ti stainless steel is non-magnetic. This alloy contains chromium, nickel and titanium.

And 1Cr18Ni9Ti stainless steel cannot be hardened by heat treatment, and has good weldability and formability. The addition of titanium makes it a suitable choice for use in welding conditions because it prevents the formation of intermetallic compounds at grain boundaries. This alloy finds applications in the aerospace, chemical and petrochemical industries.

Can 1Cr18Ni9Ti stainless steel withstand high temperature?

1Cr18Ni9Ti stainless steel is Ni-Cr-Mo type austenitic stainless steel, its performance is very similar to 304, but due to the addition of

Metal titanium makes it have better grain boundary corrosion resistance and high temperature strength. Due to the addition of titanium metal, it effectively controls

the formation of chromium carbide. Therefore, 1Cr18Ni9Ti stainless steel has excellent high temperature resistance.

What are the applications of 1Cr18Ni9Ti stainless steel?

1Cr18Ni9Ti Stainless Steel is an austenitic stainless steel that offers excellent corrosion resistance while maintaining good mechanical properties. This alloy is used in a wide range of applications from automotive to medical. Some of the most common uses for 1Cr18Ni9Ti stainless steel include:

- Car exhaust system

- Food processing equipment

- medical equipment

- Chemical processing equipment

1Cr18Ni9Ti stainless steel combines excellent corrosion resistance with good mechanical properties, making it ideal for a wide range of applications. If you need an austenitic stainless steel that can withstand harsh conditions, 1Cr18Ni9Ti stainless steel is the alloy for you.

What is the difference between 1Cr18Ni9Ti and 0Cr18Ni9?

China's 1Cr18Ni9Ti is equivalent to American AISI1Cr18Ni9Ti, 0Cr18Ni9 is equivalent to AISI304, 1Cr18Ni9 is equivalent to 302, 0Cr17Ni12Mo2 (new number 022Cr17Ni12Mo2) is equivalent to AISI316

1Cr18Ni9Ti=China Taiwan 1Cr18Ni9Ti=International Standard X7CrNiTi18-10=Russia 12X18H10T=Japan SUS1Cr18Ni9Ti=Germany X6CrNi18-10=American ASTM A276 1Cr18Ni9Ti

If it is used at a high temperature of 700 °C, 1Cr18Ni9Ti should be competent, because it is not only an austenitic stainless steel, but also a widely used austenitic heat-strength steel, but it is best not to exceed 750 °C, and its heat treatment is solution treatment , That is, heating to above 1000°C, water quenching after holding for a certain period of time, and then aging at a temperature 60~100°C higher than the use temperature.

The carbon content of the two is different, 1Cr18Ni9Ti is high. The content of chromium and nickel is the same, 18% and 9% respectively.

In this case, due to the low carbon content of 0Cr18Ni9, its strength is lower than that of 1Cr18Ni9Ti, and its corrosion resistance is better than that of 1Cr18Ni9Ti. However, since 1Cr18Ni9Ti contains titanium that resists intergranular corrosion, it can be improved by heat treatment to resist intergranular corrosion. It can be used as a substitute under normal temperature conditions.
