不锈钢管厂家:硬度检测
Hardness testing
不锈钢管的内径在6.0mm以上,壁厚在13mm以下的退火不锈钢管材,可以采用W-B75型韦氏硬度计,它测试非常快速、简便,适于对不锈钢管材做快速无损的合格检验.不锈钢管内径大于30mm,壁厚大于1.2mm的不锈钢管,采用洛氏硬度计,测试HRB、HRC硬度.不锈钢管内径大于30mm,壁厚小于1.2mm的不锈钢管,采用表面洛氏硬度计,测试HRT或HRN硬度.内径小于0mm,大于4.8mm的不锈钢管,采用管材专用洛氏硬度计,测试HR15T硬度.当不锈钢管内径大于26mm时,还可以用洛氏或表面洛氏硬度计测试管材内壁的硬度.
W-B75 type Wechsler hardness tester can be used for annealed stainless steel pipes with inner diameter over 6.0 mm and wall thickness under 13 mm. It is very fast and easy to test. It is suitable for rapid and non-destructive inspection of stainless steel pipes. Stainless steel pipes with inner diameter over 30 mm and wall thickness over 1.2 mm are tested by Rockwell hardness tester for HRB and H. RC hardness. Stainless steel pipes with diameter greater than 30 mm and wall thickness less than 1.2 mm are tested by surface Rockwell hardness tester. Stainless steel pipes with inner diameter less than 0 mm and larger than 4.8 mm are tested by special Rockwell hardness tester. When the diameter of stainless steel pipes is greater than 26 mm, Rockwell hardness tester or surface Rockwell hardness tester can also be used. Hardness of the inner wall of the pipe.
