What is the difference between titanium alloy and stainless steel?

The difference between titanium and stainless steel:
Different composition: Titanium alloy is an alloy composed of other elements on the basis of titanium, while stainless steel is resistant to steam, water, air and other weak corrosive medium or stainless steel with stainless steel;
The properties are different: the plasticity, strength and thermal strength of titanium alloy are relatively high, and the corrosion resistance is good, while the stainless steel has weldability, polishing and corrosion resistance.
Titanium alloy is mainly used in aircraft engine compressor components, while stainless steel is widely used in building decoration, water industry, automotive industry, food machinery, energy, electrical appliances and so on.
Different temperature resistance: titanium alloy high temperature resistance, melting point is 1942k, higher than steel nearly 500k, higher than gold nearly 1000k, and most of the stainless steel temperature limit is 800 degrees;
Acid and alkali corrosion resistance is different: Titanium alloy has a strong acid and alkali corrosion resistance, and will not be corroded in seawater for five years, while some stainless steel is corroded in seawater.

The difference between titanium alloy and stainless steel can be in terms of its composition and performance, but these differences are fundamentally different in their composition.

Titanium alloy, as the name suggests, is an alloy formed by adding other elements on the basis of titanium; Stainless steel Everyone knows that the main component is iron, the basic component is chromium, and then there are nickel, manganese, carbon, etc., the number of these components determines the performance difference of stainless steel.

In general, titanium alloy has high strength, good heat resistance and strong corrosion resistance;

Stainless steel has weldability, polish and corrosion resistance.

Although many performance titanium alloys are better than stainless steel, it does not mean that all fasteners or mechanical parts should be used in titanium alloys, or according to the use of the environment and procurement costs, the cost of titanium alloys is generally higher than that of stainless steel.

Therefore, in the case that stainless steel can meet the needs of use, there is no need to use titanium alloy, unless it has special requirements for heat resistance.

Like our fastener industry, stainless steel is a commonly used material, which can basically meet a variety of needs, and we will use titanium alloy steel when users have special needs.
