1.1 The corresponding technical specifications of the industry and the World Health Organization are in accordance with the standards, 1.? The test control hair can be added by means of fast twisting, etc., and the heat treatment must be carried out around the test day. The measurement must be clear and the heat treatment area and deformation wind
1.3 Integrity for these test days, when the light is not greater than s2m, the gloss is 10+9mm, when the light is greater than 32mm, H is 14±2mm
1.4 The entire technical component is treated in the specified heat treatment environment and then opened. 1.5 The front donation along the stop diameter is two-tenths *-shaped brand or ""-shaped (rising or using *"-shaped refers to), the remaining degree should conform to the vertical diameter m, 1~6.
Beijing light ten 2 times, 6-m
[.6 Zhang chooses the place, the doctor will put the fine mouth space down straight, the excellent small mouth and the solution of the user's heart, the benefit of Sichuan scholar's method play point to save the later hit the place
1. In the test evaluation of the hit, the cumulative improvement should be generally kept, the blue free break surface worry, the sale and the production are relatively The person's type of checking base area, the guarantee of rating accuracy,
2 blue elastic should
2.1 use good staff to carefully observe the electricity fee, if the division is not clear, the following payment can be urged for a large lack of reading. 22 The certificate of the division, the 1H/14999, 5 business estimate gold assumption, high times the period standard certificate level full> attached to the school several evaluation teaching to plan the design of the construction of the special case defects,
3 thank the evaluation of the organization's incentive
. 1 magic grab, the east fracture on the level of the organization, its characteristics under the effectiveness of the policy belt we maintain the company. The existing will be a light and school shape of the steel, and there is a bad alloy through the continuous battle, the most according to this record change policy can be a good number of good work situation to the serious process of the complete frost level plan, 2 stratification, the fracture of the news presents the home color. Light color release cup fruit color collection, the beauty of the medical north will get a new shape of the super style, and the most ring of the gold organization of the description of the continuous trap and think that the points show. Re-determine the use of || t 4.1 Fracture or inspection Figure 1IGH4089, GT1AIR7 alloy Science: Applicable to G1T4049 alloy Figure Applicable to H443 alloy Figure 4 Applicable to high-quality alloys and defective and convex alloys Approved by 1994101# box Applicable to three leading countries and Australia Some merchants can cooperate with the previous period of this standard. This standard value is read by the steel mills in the period of this standard. This standard is entrusted to the Standardization Research Institute of the Ministry of Metallurgical Industry for interpretation.
