ISO 3581-A-E(19 9 Nb)B 4 2

Introduction：

A137 is a Cr19Ni10Nb stainless steel welding electrode with basic coating containing NB stabilizer. It adopts DCEP connection method and is permitted for welding at all positions. The product has excellent weld intercryctalline corrosion resistance.

Purpose：

The product is applicable for welding the important corrosion-resistant and Ti-containing stable 06Cr18Ni11Ti stainless steel.

It is suitable for welding of 18%Cr-8%Ni-Nb and 18%Cr-8%Ni-Ti stainless steel structure, mainly used in petrochemical industry, pressure vessel, food machinery, medical equipment, fertilizer and other industries, welding SUS347, SUS321.

2. Impurities such as rust, oil stain and moisture must be cleared off of the work piece before welding.

Welding Position:

What you cover in your shipping policy and how you communicate it will be highly dependent on your current business operations and supply chain. The goal is to be transparent with customers.

As 2020 brings unforeseen shipping delays and increased carrier costs, it's more important than ever to keep your shipping policy up to date with the following key points in mind:

Essential shipping details are easy to find. While it is common practice to keep a link to your shipping policy page in the footer of your website, consider how you can also surface important shipping details in the right place at the right time (e.g. on your product page or website banner).
Clear and concise presentation. Don’t make customers comb through your shipping policy page for the information they need. Whenever possible, make it easy to navigate with clear subheadings, tables, bolded text, and links to learn more.
Order processing times. After an order is placed, how many days will it take to get it ready to ship? It’s worth communicating if you’re excluding weekends and/or holidays, and if you have certain cutoff times for processing orders (e.g. orders received after 5pm will be processed the next business day). If changes occur within your supply chain, due to peak periods or as a result of COVID-19, you should update your processing times to reflect it.
Domestic and international shipping options. What are the qualifying regions for your domestic shipping options? International shipping can be broken down in its own section where you list the countries you ship to and estimated delivery timelines. If you offer several shipping options, you can list them in a table so the information is easy to scan. Shipping costs. Break down your shipping costs for the customer. If you have a free shipping threshold, you can communicate in various places as an incentive for customers. Any potential surprise fees should be surfaced too, such as duties and taxes the customer may incur.
