抛丸名词解释：

抛丸也是一种机械方面的表面处理工艺的名称，类似的工艺还有喷砂和喷丸。 抛丸是一个冷处理过程，分为抛丸清理和抛丸强化，抛丸清理顾名思义是为了去除表面氧化皮等杂质提高外观质量，抛丸强化就是利用高速运动的弹丸（60-110m/s）流连续冲击被强化工件表面，迫使靶材表面和表层（0.10-0.85mm）在循环性变形过程中发生以下变化：1.显微组织结构发生改性；2.非均匀的塑变外表层引入残余压应力，内表层产生残余拉应力；3.外表面粗糙度发生变化（Ra Rz）。影响：可提高材料/零件疲劳断裂抗力，防止疲劳失效，塑性变形与脆断，提高疲劳寿命。

产品描述：

Electronics Inc. (EI) manufactures and maintains the world’s largest inventory of Almen strips for global distribution. EI can provide strips to any specification, from standard MIL to rigid aerospace specifications. Almen “A”, “N” or “C” strips in Grades 3™, 2™, 1™ and 1-S™ are ready-to-use and are pre-qualified. Our “A” and “N” Almen strips have the lot number printed on both sides and a patented coverage check finish. These features add value to a quality shot peening process.

The Double-Sided Numbering System

• Ensures that the lot number is legible after peening
• Provides room for notes; for example, print numbers, procedure numbers, the date and the arc height reading
• Gives a tracking method for meeting specifications, ISO and Nadcap audit requirements, and first-in, first-out requirements
• Allows lot-to-lot comparison for process consistency
• Part of Electronics Inc.’s comprehensive traceability and audit program
• Denotes genuine EI product
• Both “A” and “N” strips have the Double-Sided Numbering System

The Coverage Check Finish (U.S. Patent No. 6,568,239)

• Lapses in coverage are easy to check visually
• Contributes to a proper rotary-flap peening technique
• Enhances capabilities of coverage checker tools
• Both “A” and “N” strips have the Coverage Check Finish

等级详细介绍

 

Almen strips are classified into 3 types: ‘A’, ‘N’, and ‘C’. They differ in their thickness but have the same width and length. The type of strip is usually specified by the part designer.

“A” strips are used for medium intensity applications. “A” strips are predominantly used for shot peening with cast shot or cut wire shot.

“N” strips are used for low intensity applications. “N” strips are used usually for glass bead and ceramic bead peening.

“C” strips are used for high intensity applications.

By Grade

Grade 3 – Bulk (A-3™, N-3™, C-3™)
 Grade 3 strips are guaranteed to meet the requirement of MIL-S-13165 (now AMS-S-13165). Type A-3 strip is guaranteed to meet National Stock Number NSN 6635-00-512-1892. Grade 3 strips are economically priced and bulk packaged.

Grade 2 – Standard (A-2™, N-2™, C-2™)
 Meets AMS-S-13165. Excess oil is removed from the Grade 2 Standard strips. The strip surfaces are then visually inspected for score marks, scratches, nicks, burrs, pits and rust. Strips are certified using a sampling inspection plan for hardness, length, width, thickness, and flatness. A dated certification of compliance is issued, signed and archived. We then package “A” and “N” strips in groups of 50 and “C” strips in groups of 25.

Grade 1 – Premium Grade (A-1™, N-1™, C-1™) 
Meets SAE J442. Electronics Incorporated performs all the inspection and packaging operations listed for Grade 2 strips. Strips are sample inspected for flatness (±.001-inch) on each side. A dated certification of compliance is issued, signed and archived. The Premium Grade 1 strips are identified by batch control number which provides traceability.

Grade 1S – Special Grade (A-1S™, N-1S™)
 Meets SAE AMS 2432B. In addition to requirements for Premium Grade 1, the Grade 1S strips are inspected to ±.0005-inch flatness tolerance of AMS 2432B. A dated certification of compliance is issued, signed and archived.

* AMS-S-13165 has been cancelled with instructions to use AMS 2430. For more information see Almen Strips FAQ.
