SIST EN 4336:2004 is the Slovenian adoption of European Standard (EN) 4336:2002 from the European Committee for Standardization (CEN). It specifies the requirements for steel FE-WA3801 (X4CrNiMn20-10-2) as filler metal for welding in wire and rod form for aerospace applications, so manufacturers and buyers know which material grade and verification rules apply.

What does SIST EN 4336:2004 specify?

SIST EN 4336:2004 sets the requirements for aerospace welding filler metal made from steel FE-WA3801 (X4CrNiMn20-10-2) and supplied as wire and rod. The document is organized as a short front matter, then clauses for scope and normative references, followed by a detailed requirements table that covers material designation, manufacture, delivery condition, inspection and qualification.

The structure matters in practice because most buying and inspection decisions are tied to the table, while clauses 1 and 2 tell you which companion standards apply.

What are the key requirements of SIST EN 4336:2004?

SIST EN 4336:2004 combines material definition, manufacturing route and verification points in one specification. For a purchaser or quality team, the important part is that the filler metal must match the named steel grade and the listed production condition before it is accepted for aerospace use.

Material identity and composition

The requirement table identifies the product as steel FE-WA3801 (X4CrNiMn20-10-2) and gives chemical composition limits for the listed alloying and impurity elements. In practice, this means the mill test documentation has to show that the chemistry fits the standard before the wire or rod can be treated as conforming material.

Form, production and delivery condition

The standard covers two product forms - wire and rod - and specifies cold drawing as the production method. It also gives the delivery condition as cold drawn and annealed, with delivery condition code U. This matters because ordering and receiving inspection need to check not just the chemistry, but also the exact supply condition.

Melting method

The table states the melting method as air melted. That gives the buyer and manufacturer a defined metallurgical route, which is important when the welding filler is controlled for aerospace service and traceability.

Dimensions and dimensional control

The document sets a limit dimension for the product and includes dimensional inspection as part of verification. In practice, this means the size of the wire or rod is not left to general trade practice; it has to be checked against the standard and the associated technical specification.

Inspection and defect verification

For external defects, residual stress, internal defects, batch uniformity, marking inspection and dimensional inspection, the standard points to EN 3879. This is important because acceptance is not based only on paperwork - the material also has to pass the inspection and batch-control provisions used for welding filler metal.

Product qualification

For product qualification, the standard refers to EN 2043 and states that the qualification programme is to be agreed between manufacturer and purchaser. In practice, qualification is a controlled agreement, not a free-form supplier declaration.

What terms does SIST EN 4336:2004 define?

• Steel FE-WA3801 (X4CrNiMn20-10-2) - the named steel grade covered by the standard for welding filler metal.
• Filler metal for welding - the material added during welding to make the joint.
• Wire and rod - the two product forms covered by the standard.
• Air melted - the melting method specified for the steel.
• Cold drawn - the production method used to make the wire and rod.
• Delivery condition code U - the code used in the standard for the stated delivery condition, which is cold drawn and annealed.
• EN 3879 - the technical specification that the standard uses for inspection and verification points.
• EN 2043 - the qualification standard used for product qualification.

Who uses SIST EN 4336:2004?

SIST EN 4336:2004 is used by aerospace material suppliers, welding filler-metal manufacturers, purchasers, and quality assurance teams. It is also relevant for inspection and certification staff who need a clear basis for accepting wire and rod intended for aerospace welding.

What changed in SIST EN 4336:2004 from the previous edition?

SIST EN 4336:2004 corresponds to EN 4336:2002 as adopted by SIST.

Which standards are used with SIST EN 4336:2004?

• EN 2043 - gives the general requirements for semi-finished product qualification, which the standard uses for product qualification.
• EN 3879 - provides the technical specification for welding filler metal, including inspection items referenced by the standard.
• EN 4258 - explains the general organization of aerospace metallic material standards and how the EN standard types are used.
• EN 4500-5 - gives the drafting and presentation rules for steel material standards.

What does the SIST EN 4336:2004 document contain?

The document is mainly a requirements table supported by a short set of clauses. It covers material designation, chemical composition limits, melting method, product form, production method, dimension control, delivery condition and use condition.

It also includes inspection-related items for external defects, residual stress, internal defects, batch uniformity, marking and dimensional inspection, with references to EN 3879. For qualification, it points to EN 2043 and says the programme is agreed between manufacturer and purchaser.

For a reader using the standard in design, purchasing or quality control, the practical value is that it ties the aerospace filler metal to one defined steel grade, one defined supply condition and a defined set of inspection references.
