2. Orta derecede korozyon direnci

Maliyet kontrol\u00fc<\/strong> Grade 3 titanium is still an important material in some industrial fields due to its characteristics of “upgraded strength and moderate cost”. However, with the development of titanium alloy technology, its share in high-demand scenarios (such as aerospace load-bearing parts and medical implants) has gradually decreased, and it has turned to focus on specific market segments – such as parts that need to balance strength and medium corrosion protection, or mid-range applications that are more sensitive to cost. When choosing Grade 3, it is necessary to give priority to evaluating the actual needs of specific working conditions for strength and corrosion resistance, avoiding cost waste caused by over-design, and preventing hidden dangers caused by insufficient performance.<\/p>\n

\n– Cold processing is easy to harden, and it needs to be carried out in stages and interspersed with annealing treatment (annealing temperature is about 700-800\u2103);
\n– Welding requires inert gas protection (such as argon) to avoid oxidation and performance degradation.<\/p>\n
\n– Performance is limited in strong acid (such as hydrochloric acid, sulfuric acid) or high-temperature chloride environments. It is recommended to apply anti-corrosion coating or use titanium alloy instead;
\n– Long-term exposure to seawater environment may cause local pitting corrosion, which requires regular inspection.<\/p>\n
