How to number centered section titles?

Question

I am trying to create sections that are centered, but still with numbering. When I center the section titles (like below), the numbering disappears.

\documentclass[twocolumn,10pt,cleanfoot]{asme2ej} \usepackage[pagestyles]{titlesec} \titleformat{\section}[block]{\bfseries\filcenter}{}{1em}{}

Any ideas on how I can do this? What I want is of the format in the image below:

You're on the right track for standard classes: use

\titleformat{\section}[block]{\bfseries\filcenter}{\thesection.}{0.5em}{}

(In my opinion, 1em is too much). With asme2ej, I don't know, as it is not part of the main distributions.
