edge surface
不规则的轮廓表面必须打磨到平滑的过
度,切割过的材料的截面必须打磨掉切
割的硬化层,表面有一个一致的外观及
密度
Irregular profiles must be grinded to
secure a smooth transition and the
cross section of the material which has
been hardened during the thermal
酸洗缓蚀剂cutting process must be removed so
the surface can obtain the dense and
uniform profile
f) 凹点与环形
Pit and

推杆锁凹点与环形坑必须充分打开
确保获得指定的清洁水平,并油漆可以
渗透。
钢材的表面质量必须满足ISO 8501 - 1
A或B级锈蚀要求。
Pits and craters must be sufficiently
opened by dressing to ensure the
specified cleanliness level is obtained
and to allow penetration of paint.
The surface quality of steel products
must meet the requirements given for
rust grade A or B in ISO 8501-1.
坑必须用刷子刷油漆填充
Craters with a width≤2 mm must be filled
by paint (brush)or dressed out
g) 材料气孔
Porosity
宽/深比小于2,且深度最大2mm
Width/depth of the porosity must
be > 2
Depth: Maximum 2 mm.
h) 脱落/氧化皮
Shelling / mill

extraneous
matter
附着的异物是不接受的
Rolled-in extraneous matter is not
acceptable
k) 凹槽与磕伤
Grooves and
gouges
如果下列要求不能满足,那么凹槽和圆
凿要矫正:宽/深>1.5深:最大2 mm
Grooves and gouges must be
dressed if the requirements listed
below are not met:
Width/depth > 1.5
Depth: maximum 2 mm
