6.热处理：
产品需要在1000度以上进行水韧处理。

产品之间的间隙至少在25MM以上。

热处理完成后，需提交以下报告：
（1）热处理炉温曲线，需要反映出保温时间，温度等信息。

（2）淬火后的水温和铸件温度
（3）装炉信息：每炉装的产品名称，数量和炉号。

（4） 所有记录需要有操作人员的签字和日期。

7.微观组织:
一个75X75X125 mm的试块将和铸件一同浇注，做附铸试块. 一同热处理，进行微观组织检测。

在试块的中心取样。

避开缩的区域.
基体组织为100%的奥氏体， 只允许在晶界上分别不连续的，孤立的碳化物，奥氏体晶粒的大小按照ASTM E112标准的1级~3级之间，碳化物的标准按照国标GB/T 13925执行，其中：
1)for undissolved carbides, Grades W1 to W3 or better are acceptable
未溶解碳化物W1~W3级合格
2)for precipitated carbides, Grades X1 to X3 or better are acceptable
沉淀碳化物X1~X3级合格
3)for overheated carbides, Grades G1 to G2 or better are acceptable
过热碳化物G1~G2 合格。

每个产品出一个金相样的报告。

8. 表面缺陷
按照标准MSS SP-55执行，允许的缺陷等级见下表。

4.6 Weld
4.6.1
No weld repair is permitted to solely improve the casting visual appearance. Reasonable
grinding is preferred to remove surface or subsurface defects when castings do not meet Section 4.5.3. Castings with cracks or hot tears that cannot be removed by grinding are to
4.6.2
For castings with defects larger than 4 square inches (25 square centimeters) or, deeper than 1 inch (25.4 mm) or a 20% of through section thickness at the defect region a request for weld repair is to be submitted to CAB Incorporated for review and approve. The request is to clearly state the defect size and position with pictures and how the factory is to perform and inspect the weld repair. A unique casting identification (ID) number is to be included in the request.
Once approved by CAB Incorporated, the factory is to follow guidelines in Section 4.6.3 and the factory proposed welding procedure to repair the defect.
Re-heat treatment maybe required after welding, per section 4.3, and if so, castings can only be re-heat treated once.
The unique casting ID is to be either stamped or tagged properly to the repaired casting.
The factory is expected to conduct manufacturing process change to improve the
casting quality if the defect is repetitive and consistent with the current process.
4.6.3 The following guidelines are to be followed to perform any weld repair for casting defects
except for those stated in Section 4.6.1:
1)it shall be done using a filler metal with similar chemical composition as in Section
2.3.1. The electrode size is to be as small as practical.
2)the defect must be fully removed by minimum grinding or arc air to ensure the proper
weld penetration to the side walls. The casting shall be rejected if a cavity shrinkage or
core shift is discovered during the excavation. Spotting weld over the top of defects is
not acceptable.
3)the base metal temperature is to be controlled to lower than 450F (232C) throughout
welding. Peen welds immediately after each pass. Alternate weld repair among several
castings are recommended to keep the casting temperature as low as possible
4)At CAB Incorporated’s discretion, an X-ray inspection to the weld repair area might
be required to verify that no significant cracks are present due to the weld repair.。
