New Developed Steel

A : Environment reaction   B : High Strength  C : Functional progress

Menu Feather Practical (Use) A B C
Ultra fine grain
steel wire
1) High strength (More than 900mpa) and High toughness by grain refining
2) Omission of Carburizing, Quenching/Tempering, Baking in Bolts, Screws
3) Excelent recyclability achieved by using non-alloy steel
・Screw for mobile phone
・High strength bolt and screw for automobile
・Screw for consumer electronics and degital equipment
 
High tensile bolt
steel wire
1) High strength and High toughness by characteristic elemnt composition
2) High strength bolt with function that untouched by the delayed fracture
3) Excellent wear resistance
4) Constribution to weight saving by strengthening
・High strength bolt for automobile  
Steel wire for tapping
screw/bolt
1) Used as Tapping screw/bolt to High strength steel plate for automobile
