1, the price is different.

Titanium gold is a precious metal, and the price is relatively expensive; Stainless steel is cheaper. ? There are many kinds of titanium alloys, different models and different prices, depending on the grain size.

2, the tolerance temperature is different

Titanium has high temperature resistance, and its melting point is 1942K, which is nearly 1000K higher than gold and nearly 500 K higher than steel. The maximum tolerance temperature of stainless steel is 800 degrees, generally not more than 600 degrees. Moreover, the hardness of titanium gold is relatively high. Generally, a "titanium submarine" made of titanium alloy can dive to a depth of 4500 meters and is not easy to be crushed; Generally, steel submarines are easily crushed by water pressure when they exceed 300 meters.

3, acid and alkali corrosion resistance

Titanium has strong acid and alkali corrosion resistance, and it will not rust after being immersed in seawater for 5 years. Steel will corrode and deteriorate in seawater. Titanium alloy is used to make hulls, and seawater can't corrode them. Only when the steel grade is selected correctly, reprocessed properly and maintained properly, stainless steel will not be corroded, pitted, rusted and worn. Stainless steel is also one of the strongest building metal materials.
