NOTES:

1. The minimum temperature for Grades B5, B6X,and B7 shall be 1100°F; for Grade
B16, 1200°F;
译文：等级为B5，B6X和B7的最小回火温度为1100°F，而等级为B16的最小回火温度为1200°F
2. To meet the tensile strength requirements, the hardness shall be over Brinell 201(Rockwell B94)minimum.
译文：硬度一定要在201布氏（94HRB）硬度以上，抗拉强度一定能达到。
3. Class 1 is solution treated-Class 1A is solution treated in the finished condition for corrosion resistance; heat treatment is critical due to physical property requirements. Class 2 is solution treated and strain-hardened. Austenitic steels in the strain-hardened condition may not show uniform properties throughout the section particularly in sizes over 3/4 in .in diameter.
译文：Class 1将其视为1级对待，Class 1A的材料应进行表面处理,具有防腐蚀性能，Class 2类的各等级的材料应接受碳化物固溶处理后应变硬化奥氏体钢,尤为3/4以上的螺栓,经硬化后可能出现整个面上各部分性能不均匀现象.
4. For diameters 3/4 in. and smaller, a maximum hardness of Brinell 241(Rockwell B 100) is permitted.
译文：直径为3/4或更小的产品，硬度要求为最大241布氏（100HRB）硬度。
5. For diameters 1-1/2 in. and larger, center(core) properties may be lower than indicated by test reports which are based on values determined at mid-radius.
译文：直径为1-1/2或更大产品，芯部性能低于试验报告所点明的性能,因为试验报告依据的数值是在半径中点处测定的。

NOTES：(备注)
1. In addition to the indicated grade marking, all grades, except A563 grade O, A and B, must be marked for manufacturer identification.
除所列等级标记外，所有等级（除A563，O、A、B级外），必需注明厂家自己标记。
2. The markings shown for all grades of A194 nuts are for cold formed and hot forged nuts. When nuts are machined from bar stock, the nut must be additionally marked with the letter‘B’.The letters H and M indicate heat the ated nuts.
A194标准，所有螺帽都是冷墩成型和热处锻造成型螺帽。当螺帽是由棒钢机械加工而成时，需在标记上加字母“B”；字母“H”和“T”表示是经热处理的螺帽。
3. Nuts are not required to be marked unless specified by the purchaser. When marked, the identification marking shall be the grade letter O, A or B.
如购货方无特殊要求，螺帽上可以不注明等级标记。如果要注明的话，等级标记为字母O、A或B。
4. Properties shown are those of non plated or non coated coarse thread hex nuts. For properties of other nut styles, nuts with fine threads, and plated or coated nuts, refer to Table 3, page B-171.
所示机械性能，是非电镀、粗牙、六角螺帽的机械性能。细牙、电镀螺帽的机械性能，参阅B171页，表3。
5. Properties shown are those of coarse thread heavy hex nuts.
所示机械性能是粗牙、重型六角螺帽的机械性能。
6. Properties shown are those of coarse thread heavy hex nuts. For properties of other nut styles and nuts with fine threads, refer to Table 3, page B-112.
所示机械性能是粗牙、重型六角螺帽的机械性能。细牙螺帽和其它类别螺帽的机械性能参阅B-112页，表3。
7. Properties shown are those of coarse and 8-pitch thread heavy hex nuts. For properties of coarse and 8-pitch hex nuts, refer to Table 3, page B-132.
所示机械性能是粗牙，牙数为8的重型六角螺帽的机械性能。粗牙，牙数为8的普通六角螺帽的机械性能参阅B132页，表3。
8. Hard-nesses are Brinell Hardness Numbers.
硬度是布氏硬度。
9. The nut manufacturer, at his option, may add other markings to indicate the use of atmospheric corrosion resistant steel.
如采用防腐蚀钢材，螺帽生产厂家可增加其它标记。
10. Specifications（详细说明）—
ASTM A563-Carbon and Alloy Steel Nuts, page B-167.
ASTM书A563-碳钢、合金钢螺帽，B-167页。
ASTM A194/A194M-Carbon and Alloy Steel Nuts for Bolts for High Pressure and High Temperature Service, page B-126.
ASTM A194/A194M –经高压、高温处理的，与螺栓配套的碳钢，合金钢螺帽。
11. Grade 2 不需打任何标记。
12. Grade 5 and 8应标记等级。

HV表示维氏硬度，是硬度的一种测量方法及单位；
KSI是千磅/平方英寸，是压强，具体地说是抗拉强度单位；
抗拉强度和硬度之间非线性关系，一般可以查表换算：

104KSI=HV220；HV250=116KSI
1 KSI = 1000 lb / in.2 = 1000 x 0.4536 x 9.8 N / (25.4 mm)2 = 6.89 N / mm2
