SIST EN 2157-2:2001 is the Slovenian standard published by SIST for the aerospace series on steel forging stock and forgings. It specifies the particular requirements for forging stock intended for making steel forgings, and it is meant for use together with EN 2157-1. The standard also covers a controlled case where bars and sections to EN 2069-3 may be used as forging stock if the manufacturer and purchaser agree.
What does SIST EN 2157-2:2001 specify?
SIST EN 2157-2:2001 specifies the particular requirements for forging stock intended for the manufacture of steel forgings. In practice, that means it is the document to check when a supplier is providing stock material for later forging, not the finished forging itself.
SIST EN 2157-2:2001 is part 2 of the Aerospace series - Steel - Forging stock and forgings - Technical specification. It is to be used with EN 2157-1, and it includes a special allowance for bars and sections conforming to EN 2069-3 when both parties agree that the requirements of this standard will still be met.
What are the key requirements of SIST EN 2157-2:2001?
SIST EN 2157-2:2001 focuses on the requirements for forging stock, so the main question for a user is whether a given steel product is acceptable as input material for making forgings. This matters because the buyer and manufacturer need a common basis for acceptance before the material is released for forging.
- The scope is limited to forging stock for steel forgings. The standard is not a general steel product document; it is aimed at stock material that will later be forged. In practice, this helps avoid using a product to the wrong specification.
- The standard is used together with EN 2157-1. That means the requirements here are not meant to stand alone. A user needs both parts to understand the full technical specification for the aerospace series.
- Bars and sections conforming to EN 2069-3 may be used as forging stock. This gives a permitted alternate material route, but only under a specific condition. For a buyer or supplier, that means the material can only be treated as acceptable forging stock when the agreement requirement is satisfied.
- An agreement is required between the forging stock manufacturer and the purchaser. This agreement is the control point for using EN 2069-3 bars and sections. In practice, it means the choice of material form is not automatic and should be documented in procurement or supply records.
- The agreement must ensure that the requirements of the present standard are met. This protects the technical intent of the document. For users, it means the alternate stock must still fit the same acceptance basis as the main standard.
- The document belongs to the aerospace series. That tells users the material is intended for aerospace-related supply chains where traceability and specification control are important in purchasing and quality assurance.
What terms does SIST EN 2157-2:2001 define?
- Forging stock - Material supplied for later forging into finished parts.
- Forgings - Parts formed by forging from stock material.
- Manufacturer - The organization supplying the forging stock.
- Purchaser - The organization buying or specifying the forging stock.
- Bars and sections - Product forms that can be used as forging stock when the agreement condition for EN 2069-3 is met.
Who uses SIST EN 2157-2:2001?
SIST EN 2157-2:2001 is used by forging stock manufacturers, forging shops, aerospace material suppliers, and purchasers who order steel stock for later forging. Quality managers and buyers use it when checking whether a proposed material form is acceptable and whether the supply agreement covers the required conditions.
What changed in SIST EN 2157-2:2001 from the previous edition?
SIST EN 2157-2:2001 is identified as identical to EN 2157-2:1993.
Which standards are used with SIST EN 2157-2:2001?
- EN 2157-1 - The companion part that SIST EN 2157-2:2001 is to be used with.
- EN 2069-3 - The standard for bars and sections that may be used as forging stock when the manufacturer and purchaser agree and the present standard’s requirements are met.
What does the SIST EN 2157-2:2001 document contain?
SIST EN 2157-2:2001 is a technical specification focused on the requirements for forging stock in the aerospace steel series. It also gives the condition under which EN 2069-3 bars and sections may be used as forging stock. For a buyer or supplier, the document serves as the technical basis for agreeing what material form can be supplied for making steel forgings.
