Mechanical Tests 机械性能测试

Mechanical tests are carried out for a correct and complete classification of materials as well as to investigate about the proper execution of production processes, heat treatment, inspection and verification of welding, welding and qualification of welders, brazers and welding operators. 

All the specimens are made at the workshop of the laboratory.

 

Tensile Tests are carried out at room temperature (RT) or at elevated temperature.

•       Tensile test at Room Temperature (ISO 6892-1, GB/T 228.1, ASTM E8/E8M, ASTM A370) 

•       Tensile test at elevated temperature (TMax +1100°C) (ISO 6892-2, GB/T 4338, ASTM E21) 

Impact Tests (Charpy pendulum impact test) are carried out at room temperature or at different temperatures to assess the transition curve "FATT"

•       Charpy pendulum impact test (Room Temperature RT - T=-196°C) (ISO 148-1, GB/T 229, ASTM E23)

•       Charpy pendulum impact test: lateral expansion + % Share (ISO 148-1, GB/T 229,  ASTM E23) 

 Hardness tests & micro hardness test 

•       Brinell, Vickers Rockwell Hardness (ISO 6506-1, ISO 6507-1, ISO 6508-1, ASTM E10,  ASTM E384, ASTM E18)  

Bend tests and/or compression test

Bend test (GB/T 232, ASTM E290)

Compression test (GB/T 7314, ASTM E9)

 

 

机械性能测试是为了检验产品是否符合规范要求，同时也检验材料是否严格按照产品生产工艺流程、热处理工艺进行、焊接检验，焊工考试，焊接工艺评定等。

为保证取样完全按照标准，所有试样都由苏州迈拓金属检测自己的加工车间进行取样加工

拉伸试验（室温或高温拉伸）

•       室温拉伸试验(ISO 6892-1, GB/T 228.1, ASTM E8/E8M, ASTM A370)

•       高温拉伸试验(TMax +1100°C) (ISO 6892-2, GB/T 4338, ASTM E21)

冲击试验（夏比摆锤冲击试验），室温或低温冲击，韧脆转变温度测定（FATT）

•       夏比摆锤冲击试验(室温RT - T=-196°C) (ISO 148-1, GB/T 229, ASTM E23)

•       侧膨胀值及剪切断面率测试 (ISO 148-1, GB/T 229, ASTM E23)

硬度测试& 显微硬度测试

•       布氏、维氏硬度(ISO 6506-1, ISO 6507-1, ISO 6508-1, ASTM E10,  ASTM E384, ASTM E18)

弯曲试验或压缩试验

弯曲试验  (GB/T 232, ASTM E290)

压缩试验  (GB/T 7314, ASTM E9)

管子的扩口和压扁试验

Tube Drift-expending test (GB/T 242, ISO 8493)

Tube Flattening test (GB/T 246, ISO 8492)
