Technical information policy

Technical Content & Review Policy

Stainless steel guides on this site are published by Tsingshan (Shandong) Iron & Steel Co., Ltd.. We identify the technical basis, update date and practical limits of each resource so buyers can use it appropriately during specification and quotation. Website guidance does not replace project engineering or contract documents.

How content is prepared

• Commercial pages separate confirmed company facts from order-specific capability, stock and delivery conditions.
• Technical summaries identify the relevant product form, delivery condition and source standard.
• Standards are summarized for buyer orientation; this site does not reproduce or replace licensed contract editions.
• Equivalents and comparisons are treated as approximate guidance, never unconditional material-substitution approval.
• Calculators provide theoretical estimates and state the assumptions that must be confirmed in a purchase order.

Sources, editions and updates

Source notes and last-updated dates appear on technical pages. Standards evolve, and requirements can vary by product form, dimensions, delivery condition and project. The purchase order must therefore identify the applicable standard, edition, supplementary requirements and project code. Before production, the buyer's qualified technical authority should confirm the selected material, acceptance criteria and controlled documents.

Engineering and procurement boundary

Website content is general procurement guidance. Final grade selection, design allowables, corrosion assessment, pressure rating, welding procedure, regulatory compliance and material substitution remain the responsibility of the buyer's qualified engineer and the applicable contract documents. Quoted supply is subject to order-specific specification review and written confirmation.

Corrections

To report a possible technical error or request the source and edition behind a statement, emailsales@tsingshansts.comwith the page URL, disputed text and the contract standard or source you are using. Material corrections are checked against the relevant source, dated and published when confirmed.
