Q: How many grades does pure titanium have?
A: Pure titanium has four distinct grades,they are: Grade1,Grade2,Grade3,Grade4
Q: What's the characteristic for Grade 1?
A: Grade 1 belongs to pure titanium which have lowest strength but highest formability and corrision resistance.Meanwhile,it also has an excellent weldability.
Q: What's the usage scenario for Grade 1?
A: Grade titanium widely applied to chemical and marine industries,specially in petrochemical plant,offshore drilling platfomr,oil and gas transportation pipeline,etc.
Q: What's the characteristic for Grade 2?
A: Grade 2 belongs to pure titanium,which have excellent corrosion resistanct in high oxidizing and midly reducing environments,but it is slightly stronger than Grade 1.Meanwhile,Grade 2 titanium offering an excellent balance of strength and ductility.
Q: What's the usage scenario for Grade 2?
A: Grade 2 titanium widely applied to chemical and offshore industries,specially in heat exchangers,ballast water system,hypochlorite system.
Q: What's the characteristic for Grade 4?
A: Grade 4 belongs to titanium too,but it has the highest strength in pure titanium,It has very excellent weldablity.
Q: What's the usage scenario for Grade 4?
A: Grade 4 titanium mainly usde in chemical and offershore industries,specially as welding wires of various specifications.
Q: What's the characteristic for Grade 5?
A: Grade 5 belongs to alloyed titanium,it has very high strnght but low ducitility,compared to pure titanium,Grade 5 has much higher tensil strength and higher yeld point.
Q: What's the usage scenrio for Grade 5?
A: Grade 5 is the most widely used in alloyed titanium,it widely used in aerospace and military industries,specially in aircraft,spacecraft,missile,armour,etc.
Q: What's the characteristic of Grade7?
A: Grade 7 belongs to alloyed titanium,it has very excellent corrossion resistant.Its mechnical properties is similar as Grade 2.
Q: What's the characterstic for Grade 7?
A: Grade 7 is mainly used in chemical and offershore industries,specially as welding tube.
Q: What's the characteristic for Grade 23?
A: Grade 23 belongs to alloyed titanium.It's kind of Grade5 which have extra lower interstital.Grade 23 also has high strength,higher yeld point but low ductility.Meanwhile,Grade 23 has a very excellent integration with human body.
Q: What's the usage scenrio for Grade 23?
A: Grade 23 mainly used in medical industrial,specially as a very excellent surgical implants,such asd bone nail,bone lamella,heart stent,etc.
